Admittedly there was a lot left to be desired for me when I made this. I spent a good deal of time just figuring out how to make procedural dungeons from scratch, and this uses the 3rd or 4th iteration. I found myself working on the rest of the systems in within the last 24-36 hours or so. I had planned to implement combat, as well as tunneling, but there just wasn’t enough time.
As far as the reset trick, I anticipated someone would figure that out. It’s a bit like scumming for good-feeling levels in Angband or something, and so that’s why the first and second levels only produce a few gems (the floor segments, and therefore chance of gems, increase the deeper you go).
I really appreciate the feedback. Thanks for playing!
