Nice. The wait time between the waves feels a bit long sometimes, and the way slimes "hit" you from afar is slightly confusing, but a pretty neat little game overall. 9.5/10
The time between the waves feels long because I wrote a script that prevent the spawner to spawning enemy if there is a bunch of enemy in the room but the code sometimes does not work so I add a time (3-5 seconds) every time another wave spawns so sometimes the enemy you can get is 6+ sometimes only 2
