Glad this game was in my queue! I quite enjoyed it quite a bit once I wrapped my head around it. I skipped the tutorial text like a punk and was punished by not understanding I could place my defenders. Once that clicked I found this to be a unique twist on tower defense and maybe the most honest implementation of "roll of the dice" that I've seen so far. Loved the cores, loved the instant power ups. I especially loved the level where you were given a completely malfunctioning core. That was cool to instantly know what I could do with it because of the way you set the levels up incrementally.
Nice work!
