You're a ninja with the ability to reverse time, but only the last 10 seconds. Your time pool (blue bar in the top left corner) regenerates as time passes.

The objective is to get past the samurai guards without being seen.

There's only 3 levels, when finishing the third level you will loop back to the first.

Controls:
Jump - Space or Right mouse button
Reverse time (hold) - Ctrl or Left mouse button
Left - A or Left arrow
Right - D or Right arrow
Respawn - Enter

There's also gamepad support, it's mapped for Xbox 360 controllers, A = Jump, X = Reverse time, Y = Respawn.

We will most likely upload an OS X build tomorrow as well, if I can figure out how to deploy it properly.

We had sound effects in the game, but it turns out that this caused horrible stuttering on Windows, and since we didn't have time to fix it we disabled sound effects on all platforms.
