Very cool game. I love how many different situations the running mechanic is good for: From hiding behind corners and only showing yourself enough to draw enemies to you so you can pick them off one by one, to stabbing your way like a badass through a roomful of ants, to running away in panic not knowing how close behind the angry mutants who want to rip you to shreds are. I used to think that Crawl's stealth mechanic was pretty good for a roguelike, but this one takes the cake. Or, rather, walks next to the cake until suddenly dashing in, grabbing it, and running away cackling like a maniac.
Took me about six or seven tries to kill the Queen. That was without using the wand or the spellbook, though I did down a potion of speed. Then I just started another game (and learned how awesome the wand is). And then another game, and another. Confound these ants, they drive me to stab ):
