Great concept. Good music. Overall I enjoyed playing and competing it.
Tutorial lacks explanation on how to jump higher by shooting orbs faster. Had to glean this knowledge from comments here. After that I completed the tutorial.
The 1 and only level seems to be designed in a way that you need to restart it to complete. What I mean is that there's a blue orb on top of the wizard, but to realize on how to get it you can't use the checkpoint that's underneath it. And it seemed you need 2 green and 2 blue orbs to jump over bolts later in the level to progress further.
To jump from a wall it seems your starting jump can't touch it, so I stayed away from a wall then pressed space to jump, then moved towards it to hit it, and then jump again. Sometimes that failed in tight ledges because there's a bit of bounciness involved so would get too close to the wall (can't jump higher) or I'd slide off the edge.
