Thanks for the comment! A couple thoughts:
- It is possible to use player positioning to your advantage by only moving the unit that is being targeted by the enemy. The rest of your units can shoot it while it is being "kited".
- I wish there was sound too. Unfortunately this was made for a 48 hour challenge and I ran out of time.
- While the spawns are random, it is possible to assert control on the map by closing down sewers, and the more sewers that are closed, the longer you can survive (and even win).
