I had fun playing this! The graphics are cute and the music is chill, it gives the game a nice atmosphere ^^
I find the "freeze" mechanic super interesting, there's good potential here... The jet-pack power up (I forgot the actual name... Thrust? What happens with the space bar, basically!) is cool too, if a bit chaotic as soon as you try to modify the direction (I don't know if it's deliberate or not, though I do find it hillarious)
I also noticed that when you jump on a platform, the character automatically bounce on the platform like it's jumping once again? I think that's why the jumps felt a bit buggy at first.
Overal I think it's a cool little game!
