Great concept and easy to pickup but really, really challenging to play. Nice world design and cool models.
I couldn't figure out how to earn the coins, I'm guessing it requires timing jumps but I didn't master it in the 5 minutes I can devote to a jam game.
Overall, a great little jam game, perhaps a slightly easier start to get players into the game would really help.
One issue I did see was sometimes the game screen had a blue cast over it and other times not, maybe a bug in the WebGL?
Overall, a very nice game. Great work!
