The mechanics here are pretty cool, I like being able to jump up much higher and collect that sort of power. The tradeoffs for certain things are interesting. There are some weird control issues like when you get a lot of jump power I bounced backwards. The jumping over obstacles is very precise and the obstacles aren't very clear. The sounds are a bit dry, like it doesn't sound like much was done with them to create them. It is a bit strange that there is large, loud intro music and then no in-game music. Overall, fun concept that could use some tuning on the mechanics.
