I love the mechanic for discovoring the overmind. Intentionally trying get your troops taken out but not too many is a clever bit of strategy. The empowering mechanic is also great because it supports the overlord portion. if you could kill all enemies you wouldn't need to find the overlord. very clever and fun. The tutorial is a bit poorly worded and long winded but anyone who's played a stratagy game before will pick up on the rules quick.
