What's up with the witches and tanks on the 3rd level? They onehit everything! I had 30 shłtshovelers and 1 (ONE) witch murdered them all in 2 seconds! I mean, come on!
Interesting game, but it definitely needs a short pre-game tutorial. The controls were confusing for me, always pushed the wrong key. Then, at week 15 it tells me that I can invert the controls. WTF, tell me such a crucial thing sooner!
Oh yeah, and it needs a "GIGA DRILL BREAKEEEER!" upgrade.
