Here are some mock up screens I did for an idea I have for a dungeon crawler. Trying to keep the controls simple while having a fun dungeon crawler. (A) button for attack, (B) button switches between Game and Map. Map shows how many Health potions you have as well as your Level. The game screen has a XP bar in the middle, a key indicator in the upper right of dungeon area as well as health bar of enemy (top of dungeon area)
Health potions are used automatically when you need them so no button needed.
More ideas would be to have gold counter, have a store screen as well as possible inventory.
This game is just in the idea phase posted to gauge interest.
