This was really cool, the very simple usage of the running, jumping and orbs in the first two levels started to make me think outside the box pretty quickly. After that I was blazing through most of the levels with a little bit of planning. It makes you feel smart when you do finally get to the end.
The only real bug I noticed was in one level where if you hit a button with an orb it toggles a block which can prevent orbs from being moved vertically between two long blue blocks, and it seems like the orb got stuck in its vertical movement form but is blocked from moving vertically so it just started spinning erratically in place.
Also kinda funny to note but in the first level it changes between the movement keys to just what to press to run. And it started with display "A" first, so I held it down and ended up running back off the edge of the map lol.
Excellent work!
