Loved this, especially the smooth & simple controls! I'd love to see tile-based FPS movement more often, especially on mobile. (And I say this even though I'm a huge fan of fast-paced, old-school FPS gameplay)
And I agree, I've often thought the classic dungeon crawler movement should be used more on mobile platforms. Not planning on it for this game, though. The graphics here are too much for mobile devices I'm sure.
