I took the liberty of purchasing this game after trying out the demo that was a available at the original site. The concepts and physics blew me away. This 2-D puzzle game was a completely new direction. The variety of puzzles and combination of items led to a challenging evolving game that slowly got harder and more satisfying. Both single player and two-player missions were exceptional not to mention battle-mode. I cannot get enough of this game. Even if I get tired or the levels and arena's provided, the level editor allows you to make custom levels to test yourself or other's whether they are puzzles or battle grounds for two players. To be fair, I have to mention that as the time I purchased the game the level editor was limited because you were unable to edit the time for a level. Of course this is likely to have changed since then. If memory serves, 15 minutes is the default. I cannot stress enough how amazing this game has proved to be. I highly recommend spending the 15 dollars! (I think thats the price) MY OPINIONS: Gameplay: 10/10 Graphics: 9/10 Puzzles: 10/10 Battles: 8.5/10 Editor: 9/10 Overall Grade: A
