Fun game with a really good artstyle. I managed to get 4th place! Unfortunately, the very detailed paralax background made it really hard to see the enemies and especially the rocks, and since there's i-frames when you get hit I ended up just not trying to dodge at all and just go straight for the coins. You should take cues from bullet hell games, where the bullets are very bright and distinct so that its fair to dodge while still being difficult. Adding a white outline to enemies and obstacles would probably be a good way to start. I think the shrinking mechanic would work better if there wasn't a meter, or at least it was longer, because there's already the trade-off of it being harder to get coins, and since its so hard to dodge enemies already it isn't super useful. I'd also make it a bit easier earlier on, and add some indicator of how the difficulty is scaling over time. Despite my criticisms, its still a very well made game!
