This was a really unique game! I really enjoyed it! The art and music are fantastic, and the movement is quite unique! Quite a refreshing experience if you ask me! It's extremely impressive how you've made procedural generation in such a small time frame, you don't see this every day! The only bug I ran into was buying since coins didn't really matter since the counter went to negatives. In my playthrough enemies would kill me really fast and a didn't really know how to kill them, so I would suggest adding a small tutorial.
Overall, I really enjoyed this unique experience!
Great Job, man!
