Nice fun game! Great work for a graduation project! The game was very polished and the art looked nice.
In terms of adding to a possible sequel I believe that is up to you! The game in its current state has a good potential to kind of go anywhere at the moment since there is no specific hook or main mechanic besides being a core platformer. However, what you have is an amazing starting base for a cool platforming project you have though. The only you got to do is find / make a cool mechanic you like and tie to your base game and a demo could come quick from that.
Nice submission and best of luck! :D
Also this made me laugh a bit lol
