Hippa-Potta Maze is a game in which you must navigate a randomly generated maze, going from the top-left corner of the maze to the bottom-right.
You may zoom in (to increase the challenge) or out (to see more of the maze), but the game becomes rather sluggish the further you zoom out (hey, what can you expect for free?).
You can choose any size maze, from 5x5, to 100x100! At the end of each maze, you are shown how many moves it took you to solve.
Also, you can turn on "breadcrumb" mode, which will show you the paths you have taken before as dotted lines.
