I don't really see the connection to the theme.
Gameplay was nice, the randomness of the spawning positions works in your favor to add difficulty. Art style is nice and clean, easy to understand.
Bugs happen, that's okay and especially in a project on such a short deadline, everyone understands that there will be unfixed bugs. Don't stress too much about it. As long as the main premise of the game can be accomplished, the bugs will mostly be ignored.
Overall a fairly fun game, Definitely think it could benefit from some chiptune back ground music and some SFX for the projectile, a really solid game though for the timeline.
