The art and game mechanics are good. I enjoyed it! I think the items could have descriptions explaining what they do.

Thank you! My idea initially was to make the items a bit mysterious and you'd have to learn about them as you use them (so no real meta-progression, more like a knowledge based progression). But for a game jam, since most people only play a single run, I can see that it would have made more sense to add descriptions, as you mentioned.
