Holy hell this is so good for your first game ever :) I definitely agree with Diego about ways of improving the UI and finding ways of explaining the mechanics in-game (I wanted to do that too in my game but not enough time lol). I really like your use of sound effects to respond to wall collisions, it would be really satisfying to also have sfx and visual effects to respond to getting a character to its endpoint. Also learning about how to do scene transitions such as a fade to black so we don't just pop into the next level are just some of the little ways of really improving presentation (hint: doing so involves a persistent game object)

I could probably have fixed the UI but I was just a little bit tired of having to rush to finish the game because well i overscoped first and wasted half the jam. I regret sending the game out 2 days ealry to fix the UI thing but i forgot about it after i already published the game. But i gonna try to make the screen fade to black before changing scene to make it feel better in later games i make and thank you for the feedback :D
