Pretty interesting platformer.
Music is very disonant, it is cool for moments of tension, and it sounds really good to create a feeling of uneasy, but it is too heavy for the entire gameplay.
For the movement of the character, I dont like that since you have the wall jump it gets stuck to the walls unless you jump; it would feel nicer if you could detach without the up jump movemet. And whe you fall it feels too slow, maybe a little acceletarion would feel nicer.
Colors are too vibrant; that magenta background really hit my eyes for so much time.
In general, the levels you preppare are pretty nice but it need a little polishing to make the experience more confortable in general.
Good job for being able to participate in the jam and being able to submit a finished project! Thats a pretty cool thing, the first jam is allways a little bit chaotic, hope you have fun with it!
