My main focus was just finishing the game this time, but upon watching this run again, I see some things that I definitely could improve on if I want to attempt a higher score. 800,000+ is a no brainer, but 900,000 might be reachable. My next highest score will probably come from Hard Mode, since that does offer better bonuses, though it is quite a bit more difficult than Normal, especially on stage 1. We'll have to see what happens from here on out.
