I think this has promise, though definitely needs more content and play testing to iron it out.
Personally, I never liked the hunger system in rogue, so constantly having to keep on top of that is no fun for me (I fully accept that's a me thing, and others view it as an essential mechanic in these kinds of games).
I'd like an indication of where a bomb's explosion will reach - maybe it just shows on the turn that you place the bomb, but some UI to help indicate where is safe would be nice.
It was tricky to use bombs effectively, the ghouls seemed to follow my movements away from bombs as I ran to safety so they weren't too useful.
