Frog gang!
The art here is wonderful, and the platforming is a little tricky but ultimately very rewarding. A lot of great level design here that requires fully understanding and even sometimes abusing the platforming mechanics. I think just a little bit of air control (it's very funny the first time you slide down a long wall past the door you're trying to go through; it's a little annoying the tenth time), and a little UI (definitely coins, an indication that the flag is saving your game, and maybe a map) would go a long way. This was a lot of fun though! Great job!
