This is a very solid, well-made game! Definitely hard at first but after some practice managed to squeeze out 40 points ( : I decided to try it out with an x-box controller and it played surprising well. My favorite aspects are the reasonable difficulty curve (especially with the ungrabbable orbs) and how the game feels like it has a decent skill cap.
My one feedback is that for controller users, an easy way to restart the game without having to reach for the mouse would be great!
