Really cute game! I didn't get to play all of it (not ashamed to say it's because I kept losing) but I like the mechanics you implemented. I originally thought the character sliding was a bug or something but actually works really well when you're jumping around trying to get up the platforms! Kinda stressful, but that's totally a good thing haha.
I also really like the art and the fact that you added background music! Well done :)
