good fun and i enjoyed it a lot, got to floor 9 on the second run. i wish weapon abilities would keep their hotbar slots if you switch between the two. in addition, i think a rare room or 1 time skill respec would be neat. i found an epic staff that was really cool but i was already a few levels deep into melee. Other unique rooms would be neat like one that stops enemies from spawning (or has impervious doors which means the more you stay in there, the longer enemies will build up) so you can heal or a shrine that biases item drops a certain way.
