This game has an interesting concept behind it, i like the idea of being able to switch control between the orb and the playable character, this allowsfor a lot of interesting platforming problems to be created and the game does that to some extent. directing the rock to an other wise unreachable ledge and then teleporting to it is a fun concept however the rock should be easier to control to make more complex platforming problems possible. Also, the game has some form of bug that occurs during some set of inputs involving the right mouse button / firing projectiles that leads to a crash. as such i have not beaten the boss as all of the 6 times that ive gotten to it at some point or another the bug would occur and the game crashes. the level design could use some work also.
In conclusion, great concept, good potential, requires polishing and bug fixes.
