this concept is awesome, the tile editor felt great to use. There isn't really any concept of a game since I can basically win no matter what, there isn't really a problem to solve, I can just slap together all the enemies and win. I would love to see it expanded so that each unit/tile has a cost? Really cool though, very very creative.
Also, it bugged out a lot with pathing, and it was relatively difficult to see what was going on.
