Fun game, getting the upgrades that increase coin spawn chance and value quickly made me op, I also increased my bounce height to the point where I fly by the shops with no chance of ever falling into them. While the dynamic of having to fall into the shops is interesting, I think it might be better to have them open up when you touch them, rather than fall into them. I also found that sometimes the only way up was a high-cost platform, maybe decreasing the chance for them until later on after you have a few upgrades is a better idea, as I often lost most of my coins I was saving up due to them, making the shop expensive at the start. Overall, really cool game and interpretation of the concept, I really enjoyed it!
