Celeste was obviously a huge inspiration for this game, and it pulls it off very well.
The art and music are very beautiful, the controls are sharp and easy to use, and it was a nice difficulty. That along with the amount of content you managed to make over the course of the jam, bravo! 🎉
The only criticism I have is one another commenter had as well, the wall jump, it just feels like it locks you to the wall sometimes. It wasn't a big deal overall though.
