Absolutely excellent atmosphere thanks to the art and sound design. My favorite enemy was the swarm of rats in a cape. Those layered backgrounds really worked well for a sense of walking through the tunnels. I wish I had seen more first-person views in the jam, since it really gives me a sense of immersion. Nice "tuntacles", by the way..
Please include a Quit button in the next build. If a user doesn't know about the alt-f4 function on Windows, it will seem like they can never escape from the cave! Also, since there is no reason the user wouldn't want to sell a treasure, including the "Are you sure you want to sell this item?" box generates an extra click multiplied over the course of all the treasures in your inventory, multiplied over the course of re-visiting the shop. It would be great if the game ended as soon as you paid off your debt. I had won by day 6, but I was a little confused since the game kept going. I hopped back and forth to quickly advance time, but the game didn't seem to end even after day 17.
I was pleasantly surprised to find I could put money INTO the bank and get a green surplus number. Would've loved to see something used with that.
Definitely my favorite art of the jam.
