I love everything about this! So cool. The art, especially the animations, like riding the yoyo, are awesome. And while the yoyo to pull yourself up has been done before, I feel like you did a really good job implementing it. Doing tricks in the air is all a cool risk/reward system to build your meter back up. The only criticism I have is that the signs did not do a great job at teaching me how/why the mechanics worked. You should make this into a full featured game!
