Momentum is a challenging platform game. I didn't want it to be too easy, so some of the later levels are a real challenge to complete. But in no way impossible. The levels are designed to gradually increase the difficulty level so that the game should (hopefully!) never feel too hard.
After you finish the game, you can go back to any level to try and collect all the candy for added challenge.
The controls are very simple. Press LEFT to increase your momentum to the left, and press RIGHT to increase your momentum to the right. Escape brings up the pause menu in game, and M mutes the sound. Press R to restart a level.
