It's a cool idea, having the failure condition be "too many things on screen" rather than running out of health or something. While it's in a pretty rough state of course, it's not nearly as bad as the title had me believe. I see potential here.

I think this had a lot of potential! Submitting something playable to a game jam is a huge accomplishment and you should be proud, you got a full game loop there, and it was pretty enjoyable. Not game related, but you could upload a few pictures of the game so that more people can find it ^^ (if I’m not mistaken you can do this after the submissions close). I hope your exams are going well! Mine are in a few weeks so I’m with you ahaha.

The concept you built off of is neat, I'd like to see where this could go.

I don't want to give bad marks to anyone but it wasn't as engaging as I hoped for - well, there was more actual gameplay than in my game, so there's that. Not having the time for doing this is horrible, I feel ya. Good work!
