I went into this game thinking i wouldn't enjoy it but i actually really did, i love the rpg feel of getting stronger and taking on better enemies, a couple of things to critique is probably; the sudden change from the weak enemies to the big horned creatures was very sudden, perhaps an enemy in between that is half as strong would be a good change of pace, the boss itself while a good challenge but there appears to have a few spots of the room he can get stuck on, other than that i quite enjoyed it, great concept.
Thanks for the long feedback. :) I think your critique is spot-on. At least another enemy type would have done the game good, and I'm not surprised the boss got stuck, as we didn't have time to iron out bugs too much either. Apparently some imps (big-horned creatures) can also get out-of-bounds.
