This is pretty neat. A bit basic as presentation goes, and unfinished and wonky, but has a weird charm. Also it got pretty high genre marks for sticking very strongly to the bit of "all the hammers/tools provide some access or mobility or both." Good show there!
It might have been nice for some of the unfinished areas without much treasure to be nixed, to avoid players taking time getting to them, but a valiant effort!
There's a few quirks--the only thing that seems to be a bug properly is that I seem to sometimes have an extra hit left even when there's no visible health.
