Spectacular. Playing with savestates, not too difficult but certainly not boring. The graphics and music selection are great and the addition of the boomerang flower and t leaf made subtle and fun changes to what felt like, more or less, traditional levels.
And the kirby boss is fuckin sick, but it has one kinda critical flaw. Kirby's hitbox is a little difficult to hit without damaging yourself, even when it looks like you're coming straight down vertically.
That was more difficult then I wanted it to be lol. Some of the jumps are really cryptic and i feel like the scroll level is WAY to fast, there's to much going on. The game kinda flashed whenever i finished a level, i'm assuming that's a glitch. Besides that it was a great Demo! 8/10! ALSO Please do me a favor, add the whole "Do The Mario" song in there somewhere please lol. SWING YOUR ARMS FROM SIDE TO SIDE!
