I've been looking for a barebones, stripped-down roguelike, and that's basically what I've been looking for, thank you for making this!
Now for some unsolicited feedback hehe -- I personally think gameplay would be better with NumPad / Calculator movement (8-directions) and maybe with a "Wait" button or similar. But that's more personal taste to be honest and I can totally get behind not using them as a counscious design decision.
Awesome work!
