Interesting idea! The game has a lot of fun potential. But the physics might be yet too capricious. Moving the orb is tedious, and it's quite difficult to target ennemis with it. Hooks and Blink are useful, but not powerful enough to change the balance. Not sure what the green cubes do either? There's also a lack of feedback (on damage taken notably) which prevent from enjoying progression, and make losing quite abrupt.
But there is still some fun to find. As I said the concept of rolling enemies is neat, and once you got the hang of it it becomes enjoyable. The chara-design is cool, and the starting area looks realy neat! Clearly the game might need some more time to be polished, but it has some cool bases already. Nice job!
