I almost finished level 5 without knowing about the duplication mechanic but last second it started happening and everything went wrong from that point on (in a good way :D)
Great game, probably the one that gave me the most fun so far. Well done!
Haha, thanks! I really tried to get that feeling of "oh no, now I need to scram" when touching a coin. If I'd had more time, I wanted to make a level where you'd be forced to go through the coins and get back quickly
