Very nice game ! I do think it can be improved by adding things such as coyote time (multiple tutorials on that on youtube) as I felt a lot of the jumps were unfair. I can't jump on slopes wich felt a bit weird and I don't think any character other than the green walls should somewhat stuck to the wall, I died multiple times like that and it was really frustrating.
Other than that as a student myself I appreciate what you managed to do in such a short span of available time, very impressive !
