You should allow jump if player left the platform a few milliseconds before or if he touch ground a few milliseconds after hitting [W] key. But great game, nice idea and looks good. 

Nice art style. I like the retro feel. Gameplay mechanics felt good.

Cool idea to freeze the time if the player jumps. It makes the game really fun to play!

I really like the game, only thing I would change is the difficulty. I think the game is too easy.

ther is a lot of bug but the game is still pretty cool

Super cool idea to freeze time when you jump. I played through the whole thing bc I was interested in where you'd take it. My only criticism is the player was too slippery -- I know he's an ice cube but I felt a bit out of control sometimes. Overall great job!
