Good Idea, Poorly executed
A nice concept, but as people have been saying the characters move too slow which results in a unresponsive control system, and also makes the game quite tedious. If you make a sequel, which I hope that you do, please speed up characters and better yet make their movement continuos instead of "block to block" - this will solve the issue of pressing a key for a millisecond too long and than having to watch helplessly as your character walks to his peral.
Also considers adding some effects such as distrotions to the board, rotations in the players point of view, gradual darkening of the screen and maybe even control reverse on higher levels (mwahaha!)
On another note, I though the graphics where good, the menus etc. were also well done. Hope this review helps, will we be seeing a sequel??
