The Mechanic is very fun but the execution was a bit lacking
Here is some feedback:
-killing the eye should play some effects as a feedback to the player
-it's hard to keep track of number of waves as all waves are the same with more enemies, effects in that aspect would elevate the experience and make clearing waves more rewarding
-an upgrade system every wave or two would make things more interesting
I hope you learnt from this project and had fun making it, good luck with your future games :D
