Arrowkeys to control, Space to Undo, R to Reset.
This is a remake of a really great maze puzzle called Double Maze. The objective of the game is to get both balls to the goal(the flag) at the same time. To do so that, you have to push the balls against the walls and change their relationship to each other.

I haven't really bug tested it very much, so it could be buggy, who knows... I did it mostly as an exercise and because it's a fun game.

The original version was done in Shockwave/Director and the concept was done by Scott Kim, it can be found on his great website Shufflebrain, along with some other nice puzzle games.
