I feel this could be expanded on and turn into quite the interesting little game, the problem is when just roaming around and roaming from room to room, having to sit and roll constantly to get the rolls you need is a bit frustrating, and it would have been nice to be able to press space or something to roll the dice instead of constantly going back and forth with the mouse.
Combat, while simple, if expanded would make for an interesting game that's for sure.
Good job.
