[@finessemcgill8504]

The final boss should've been named "Bedeviled Egg".

[@narcologer5375]

Excellent name for the 07th boss, I should have done it in the source code as well)

[@voril6681]

You missed the boss between 6 and 7

[@rasylannethompson7841]

Egghead is no more.

[@narcologer5375]

Btw, 3rd's internal name is Headliss)

[@kimarykorlumiose7728]

"demonic eggman" why did they have to pass up "Deviled Eggman"

[@lewisspring35]

HOLY SHIT THATS LITERALLY PERFECT.

[@CherryChrii]

WAIT LET HIM COOK

[@franciscovillalonga7855]

eggman escaped again with his egg mobile again and again is true

[@ShaneDouglas713]

Sounds more fitting...

[@TruthSeeker23099]

Damn missed opportunity

[@arcengal]

I sure as heck didn't have "Sonic fights Castlevania bosses" on my 2023 bingo card.

[@SmeddyTooBestChannel]

this hack's been in development for a few years now though

[@Jarock316]

Except Arthur and Firebrand are part of the Ghosts 'n Goblins series by Capcom, not Castlevania.

[@callmezeldaonemoartime]

@@Jarock316 as Astaroth kek

[@ariesforce1988]

You're totally right! XD Also, 69th like. :)

[@Noname-ud4he]

@damarfadlan9251or Mickey Mouse

[@SmeddyTooBestChannel]

i'm so glad that they finished this. it's a hack that has a stupid base concept but absolutely SLAYS in the execution.

[@ToxicTaka]

@Nyan Htet Aung from what I see and what I know: Sega - Sonic series Capcom - Ghosts and Goblins series (Boss 1, 2, 4, 6 with Princess, 8, Shielder, "Cerebus") ??? - Rusty [PC-98] (Queen of the Dark Knight theme for Stage 1, another theme for Boss 6) Konami - Castlevania Series (Boss 5, Boss 6 with Tombstones and ... Sypha?, Death, Stage 4 theme of Gears Go Awry, Werewolf, Armors, Worm [?] Shaft, Aria of Sorrow clocktower theme the 2nd MG stage), maybe Rocket Knight/Sparkster series? (Boss 3; head looks like one of the floating Pig heads found in the Space shmup levels, but I may be wrong) Disney - Mickey Mouse (Boss 6 reference) ??? - Batman Animated Series game (Boss 6 reference, the Cat I believe) But yeah: it's basically a giant mashup but it honestly looks well done. I kinda miss seeing these kinds of games, but then again I may just have experienced most of them through flash.

[@ToxicTaka]

@Nyan Htet Aung yeah; sorry for the presentation of the breakdown btw. Im a little scatterbrained so when taking notes I just get info down as fast (and as sloppy) as possible so I don't miss anything.

[@setsers1]

A stupid base concept? I disagree. This become my favourite as soon as I checked it out. A dark take on Sonic can be good if done right. This is one of those examples.

[@goldenzinho19]

I know no one will answer me, but they could release a Portuguese version. Observation: that I'm Brazilian

[@goldenzinho19]

@Nyan Htet Aung yes bro, your name it doesn't look much like an American, but it would be good if they made a version in Portuguese, because I don't understand much English

[@papouligaming9594]

34:00 BFG-10,000 from Doom Eternal. I identified this track literally by the first few notes.

[@LokiThePug]

"I'll make this quick" *Proceeds to have the longest fight in the hack*

[@Thr33Sh33ts]

Never knew this existed - but it looks a lot of fun, and you handled those bosses quite eloquently.

[@arthursnyder6935]

I like how the first part of the Demonic Eggman fight is similar to what the bosses of Leaf Storm and Huge Crisis from Sonic Rush would look like if they were in a Genesis game

[@christophercolon1933]

This was actually the first one with blood with blood the HP is the blood so it’s a prize

[@malachiallen1517]

I really love the 2nd phase of Deominc Eggman just bc of the fact that it's in 3D and that it resembles the Time Eater boss from Sonic Generations, easily one of the most clever boss fights made in Romhack history

[@sonicsynthwave]

And don't forget secret rings

[@maude7420]

It's basically a storybook game and a classic game two in one Pretty cool

[@eggyboopkins7563]

Before the witch fight, there's a missing midboss that's a port of Castlevania Bloodlines' silhouette demon (from stage 5). Gotta love sonic x castlevania, with all the fantasical foes he's faced, this almost seems like a fitting crossover! -Too bad halloween is still 8 months too early-

[@arthursnyder6935]

Especially with Death because of the scene in the Belmonts' reveal trailer for Smash Ultimate where he "kills" Luigi

[@andrewowens4421]

While definitely dark for a mainline sonic game, it works really well gameplay wise. It really is "If Sonic was in Castlevania"

[@JoeNose8]

If they just made the stuff a bit more cartoony and the bosses didn't explode into gore, it feels like it would be a good halloween special edition game

[@SonicTheDutchHedgehog]

The bosses in this hack are extremely fun, the final boss is also just really impressive!

[@imheathjrscott6784]

Hands down Death has the best boss theme in here I love it I need to find this ost soon good work

[@CyborgSelZero]

Death's Theme is "Imhotep" by Gerry Trevino.

[@corndogthehedgehog277]

12:39 Sinn... Sin city wasn't made for you.

[@MetalPcAngel]

Demonic Eggman looks like he could fit right in DOOM 2016

[@RobodudeX01]

That was unbelievable. Stellar playing. Cracking soundtrack. And that Shaft fight was amazing. "Oh the Sonic boss didn't work, quick get the Castlevania boss out!" Amazing.

[@DerrickPage465]

And I like the gameplay for some parts before a boss fight begins!

[@jackmandeville-williams3621]

I must say, I could totally see Eggman doing this. He's gone to the lengths of summoning all these gods to defeat Sonic. Chaos, Dark Gaia, the dragon at the end of Superstars, the Time Eater, and many more. I could totally see him going to this length, especially seeing as he seems a bit more in his mindset from Unleashed, where he was going to try and kill Sonic.

[@jackmandeville-williams3621]

Okay, I just looked at the final boss, Eggman didn't mention wanting to kill Sonic, so I really should've checked that. Plus, I don't think Eggman would summon Satan, but probably a deity like Satan, I dunno.

[@CyborgSelZero]

Any idea where Death's and Eggman's boss theme come from? EDIT: Found Eggman's theme. It's an original composition by Gerry Trevino. It's called "Through Hell and Fire". EDIT2: Death's theme is also from him. Track is called "Imhotep".

[@saddemon3913]

Oh god, this is incredible game with dark atmosphere about Sonic, usualy everyone making those with Mario like Super Mario Fusion Revival

[@RedSpade37]

I vaguely remember hearing about this, but forgot about it, and I am so glad the Algorithm reminded me! This is unapologetically amazing, and reminds me of daydreaming about famous video game characters all battling it out!

[@Arkeo36]

The music is incredibly good.

[@ahmedtta3914]

I love when they added death from castlevania

[@darienb1127]

You could say that Robotnick became a... Deviled Egg.

[@vvlaze]

Quick warning for any photosensitive people, some of the bosses present (namely the animations during the death fight) have flashing lights, so be careful when viewing.

[@LoiValdes]

Castlevania and Sonic fans must be having a blast with this hack

[@spadez808]

This is siiick. Definitely want to give this a play lol.

[@witchymaoki5165]

i can't believe they finally finished it

[@WhatTheFnu]

This is an amusing concept, but this hack has a problem with bosses that refuse to let you hit them. There is SO. MUCH. WAITING.

[@gravitybeetle4921]

I must say, I'm only watching this because I kept taking so much damage from the Astaroth fight I couldn't ever survive the battle with Metal Sonic. But I am also seeing some differences in the appearances of Evil Arthur and Astaroth. For one, when I played it, Arthur had a pair of horns and a devil's tail on him. And another thing, the face on Astaroth's chest was much more clearly visible. Also, now that I've seen him, Gloam has actually had some of those tricks, such as turning into who I presume to be Guinevere, Arthur's supposed love interest.

[@erainmartinez8175]

The best final boss ever

[@furretbrando]

Eggman: "I'm gonna be the King of Hell! It will be me!"

[@magnumbishongledabach2002]

Death is one of all best bosses in this game, it's my favorite.

Shadow would have taken this assignment but he thought it was too incomprehensibly edgy. That and both his gun and roller blades broke at the same time.

[@berdo2595]

Na verdade, se Sonic fizesse um crossover com Castlevania. Tinha um projeto de porte de Sonic pro SNES, mas não sei se vai para frente.

[@iguro-sonic]

This is like a Fusion of Sonic the Hedgehog and Castlevania

[@ham-burger4453]

And ghouls 'n ghosts

[@ClexYoshi]

I continue to be both impressed and flabbergasted by the likes of Hellfire Saga, which CLEARLY has so much effort put into it, and yet the boss design that this hack hangs it's hat on all comes fromt he school of design that many lambasted Sonic 4 Episode 2 for; bosses that stay invulnerable for protracted amounts of time while you are forced to dodge their crap for extended periods of time until a brief vulnerability period opens up. (I feel like if anything, Freedom Planet/Freedom Planet 2 really solves my misgivings with Sonic boss design and it's hard to find the right balance when your gameplay consists of jumping into foes.)

[@ParaPatron]

Cool game🎮👍

[@zexalsrevenge511]

If you had replaced the OST with tracks from Deathsmiles, no one would’ve blinked. Not to mention, that game’s soundtrack would fit perfectly with a horror themed Sonic fan game.

[@vulnus7507]

Thats what made most stuff really easy principaly the final boss the claw atack you can literaly pause the game to see the patern

[@Jucei.]

The game was extremely difficult in it's earlier versions that a ton of people were complaining. Personally, I thought that was the appeal of the hack, so I'm a bit disappointed.

[@thebrazillianguytm2186]

@@Jucei. that's why you should be selective about what kind of criticisim you hear And let's face it, if you have to tell the player every 5 minutes what they should do in a boss fight, you probably don't have a very well desinged boss fight
