I like this prototype a lot. It's compatible with hundreds of controllers, since it won't interfere with JoyToKey.
It's a lot of fun moving around. It reminds me of Tony Hawk Pro Skater games. Unfortunately (like those games) I found the difficulty to be too great. On the first level, I have had multiple situations where I was only able to collect 44/45 orbs. It was driving me crazy.
I could indeed see myself buying this, if the game was more forgiving.
