At the wave part (4:35 - 5:08) there's a lot of space to put some iconic nine circles gameplay (E.G: Memory wave, Slow tight wave, Saw spam, Mini saw, And long upside down wave) other then that and some minor changes the level looks pretty good, i would suggest starting to think about the color pallet for the nine circles deco and maybe starting to structure all the unstructured parts, other then that the level looks really fun and i cant wait for p.3 :)
