Hey, the game was pretty good, I liked the retro graphics. The game did get a bit repetetive, especially with all of the back tracking you had to do. I felt like I saw every area five times over, and the tight platforming made backtracking tedious. I was however determined to complete the game, then collisions broke and I got stuck in the floor...

I can't move there, and reopening the game cleared my progress... 

So great job with the retro aesthetic, and impressive that you submitted so early, but the game could have used some extra polish. Still worthwhile playing =)
