Jiroku

Jiroku is a 2-D Platformer in which you try to reach the end of the map. The exciting part is that you have to maneuver through the map without touching any red blocks, and dodging enemy attacks later on in the level. Aside from running and jumping, you also have the ability to change your gravity into any of the four directions. You can only switch once per ground contact though, so be careful not to outplay yourself, while you are on your way to the goal.
