Nice game, and well done on participating in the jam, I just have a few suggestions;
- I tried to adjust the in-game volume and touching the slider muted the background audio.
- There's an issue where the shop will open twice in a row (perhaps because you still have velocity towards the button?)
- It's hard to tell when you're taking damage; I wound up dead a number of times and I'm not sure what was killing me. First person games are very notorious for this.
- Jump pads wouldn't always give me the height I needed, maybe because I hit the wall on the way up?
