DOS Games Discussion

It's a DOS game in 1980s.
Basically you navigate through different simple 2D maps, attack monsters using arrows or bombs, get treasure from bags or corpses.
Some portals to other maps are hidden. Some treasure allow you have shield against monsters.
Any ideas?

Robomaze 3 or Hoosier City

I found it. It's called "Gemstone healer".
It's for Apple II and Commodore 64, not DOS (my mistake in original post).
