Timmy the timer got taped to a time bomb!  Or something like that.  Story and major art updates tbd.  The important thing is he only has ten seconds to reach a green square at the end of the room.  Luckily, in addition to WASD and space to jump and wall jump around (first mechanic is platforming) he can also click the left mouse button to toggle if time is paused or playing forward, and hold right mouse to reverse time, causing the world around him to move backward in time independent of his own movement! (second mechanic time control).

Find ways to use the movement of the objects in the world at different times to move over spikes, ride over tall walls, or provide a wall jump surface.  Just try not to get crushed or land on spikes!
