This is a clever concept :O
The dungeon was too unforgiving, though. It was too hard to get gems and sustain the business.
Perhaps you can introduce the traps and enemies slowly as you go deeper into the dungeons to find more gems. I had too many lasers and I am not sure how to get past them at all. Is the dungeon perhaps generated every time?
You guys did awesome for a one-week game! Great work!
