Pretty cool! I like the riff on the motif for the battle music theme vs the exploration theme.
I am unfortunately too impatient to wait 30 seconds multiple times for die rolls in order to open the appropriate doors, so after collecting 2 of the powerups (which felt very rewarding!) I unfortunately succumbed to the inevitable onslaught of enemies. With some additional control over the doors or a way to simply speed up the rolls I'd want to play this through to the end!
