Beat it after a couple tries! (In 385 turns, dunno if it is slow or not). Pretty solid, honestly; it had me hooked very fast with its mechanics (it did take me a couple runs to not die in the very first floors due to turns, but from that point on it was very fun) and the enemy design (you did so good with the limited space, they did awake the imagination). When I reached the end I was kinda sad it was already over.
My only "problem" is that... I never used any Power at all. They were both quite scarce and didn't sound useful.
(I found a glitch in one of the runs, too. I got to the stairs in the turn I was actually going to run out of turns, and in the next floor I was alive. The counter did say 0, but I didn't move before killing an enemy, so I don't know if walking would have been a game over.)
