I struggled quite a bit. I had saved up 1500 gold, but I was only able to buy a bit of health and speed from the shop in the first level. When I played again, I realized the shop on level 2 was on the left after going down. I don’t remember the exact location in level 3, but I did manage to find it as well. It ended up being one of the few jam games I played all the way through without getting bored. Congrats again!
