Oh I love the animation + graphics and overall vibes of this. It all makes a really cohesive tone, and is just generally pleasant to look at and play. I like the slipperiness of the ice, it definitely makes it feel like ice. Something I think could be cool to try would be giving each of the characters dialogue. It would add some extra flavor, and a really simple way to add a ton of story/characterization. The only weird thing, which the other comments noticed as well, is that the jump is a bit tricky, and doesn't work when you have another key pressed. This made jumping on such tight platforms a little tricky, and I think could be improved upon. Overall, really good job! Love the way this looks
