Unfortunately it seems pretty broken. On entering the cave, I don't get very far before the walls bug out, and I try to keep going it just seems to put me outside the level. Which doesn't apear to be very large. I never encountered any monsters.
I liked the visual style though, and the audio. Had a Chex Quest vibe. I was ready to bash some Flemoids with a hammer.
Let me know if you can get it working, I'd be happy to try it again.
