was a little confused by the controls because my Ludum Dare Game Jam #58 entry was also a dungeon crawler but it had the rotate and strafe buttons reversed (e.g. Q/E to move sideways, A/D to rotate) XD
if there's one feature i really, really wish it had it would be a minimap - there was a lot to explore and i felt compelled to explore it all but there was just so much to keep track of ^_^;
