This is an action-puzzle game. Find your way to pass the levels. A lot of mathematical elements are integrated in the puzzles.

* Simple to play. Using only three keys, you can make the character run, jump, climb, teleport, solve puzzles etc..

* The puzzles involve arithmetic, coordinates, functions, plane and solid geometry, equations, sequences, simple calculus, as well as teleporter, antigravity, role shrinker and expander etc..

Fixed a bug that the character will auto-run sometimes when press key quickly. It's OK now, have fun!
