It's a game based on the Megazeux Encyclopedia's "Momentum" engine, where holding left or right will speed or slow horizontal velocity and holding up or down will speed or slow vertical velocity.

All this is, is a game with three "difficulty" modes which consist of two levels each, amounting to six levels... of navigating through barely decorated boards with the "momentum" engine running. That's all. No enemies, nothing to make the game more interesting. After you make it to the other end of a level it takes you back to the difficulty select screen.

I give the author props for making the game not ever grind to a halt, letting you play each level as many times as you want in one game session. However, given that this barely qualifies as a game it must not have been difficult to design it in that fashion.

Crap. 1 star.
