Man I've been playing this for four hours now, this rocks. Such a fun and addictive concept, great controls that fit the game very well (the slight air control allowing you to get to a ledge directly above is a great feature for example), and it looks and sounds really nice too. I especially like how you can set your own difficulty level in a sense: by jumping only when you need to and focusing on removing obstacles you earn points slowly but more easily, while on the other hand you can jump constantly to spawn coins faster, making the level more dangerous in the process.
I hope this gets a high rank because it's definitely the game I've played the longest while browsing these entries!
