I feel there's a really solid concept here that would be gold with a bit more polish! I really enjoyed this game, the bouncy music choice, and the art style. The plot was also pretty funny and a great combination for the game design. I really love the amount you can do with this idea!
A few things that bothered me were how early on it's just guaranteed you can't get very far and are forced to repeat the same portion until you get enough money making you just feel stuck at various loops with increasingly long return times. I feel the early game required item costs could be lowered, or perhaps some rebalancing to give the chance to survive to the top. Looking at other roguelites typically you can't beat them on the first go, but you know a really experienced player might have the ability to. It makes it feel more about skill than just raw abilities. I say that because I think post-jam you could definitely keep working on this game and get a lovely bite-sized release with tons of polish and a solid core!
I really hope you keep this one going, I had a great time playing it, great job!
