I like the concept, and the game is a lot like old flash games where you had to steer your mouse to avoid walls, with a fresh twist.
The main problem though is it needs a lot of polish, like tightening the controls and making the ghost side spawn where you last were instead of the center of the screen. The "Press B to open the door" part also seemed a little too easy?
Still, this is very good for a first jam game!
