Thanks for this! Some notes:
- food clock is kind of arbitrary (I went four levels without finding any food), or else I'm just not diving nearly fast enough.
- game crashed when I descended from level 16
- the only difference I can figure out between various monsters are: some are stationary, some wander, and some chase you. I can't tell whether they all steal money from you or steal items or just some of them.
Fun overall, I'm happy to have paid the $5 just for the chiptune Holst.
I'm really sorry about the crash! See my comment here: https://news.ycombinator.com/item?id=42093590
I have fixed the bug and if you do a hard refresh you should get the fixed version.
