Mos has lots of surprises and some are the tiny details. Speed running through the levels is challenging and rewarding. The quest aspect when looking for skulls or day charms adds another layer to the game. Quite often, any given level is actually twice as big as you first notice due to hidden passages. There is also an adventure-like quest that involves activating some kind of warp maze - which I havent solved yet. Great game.
