Well its still a great effort in the time you had.
You got the core loop down and that's the main thing right.
End of wave screen is a cool idea.
Was the player teleporting to the mouse after you shoot intentional?
Nah, another bit of polish I never got around to lol
It looks kind of cool but would be nicer if it was smoother, a knockback from the bullet effect etc
So more of a tween to position I guess would be cool.
