Pretty cool game!
Definitely its strongest aspect is the aesthetic. Everything feels pretty consistent, tasteful, and deliberate. There's tons of visual feedback and clarity for the player, very well done!
In terms of sound, I would've liked some more variation in the music. It gets a bit repetitive after a while! But otherwise, the sound effects are good and provide clear feedback while feeding into the aesthetic of the game.
Gameplaywise, I liked that the difficulty seemed to increase as time went on. The only thing I'd say is that it was a bit unclear to me how exactly the jump worked, because sometimes it left me feeling like I jumped to somewhere I didn't want to jump. Maybe that's a me thing, but I didn't quite figure it out!
Overall, great game. Congratulations, keep up the good work!
