Hardest thing was getting from menu :D
But overall very original concept but could be developed so much more. For example make the maze bigger and make walls of different color, based where you are i the maze. Then player will know, that he/she must get to the good segment first and then wind the other tank. This was player will not get totally lost (like if the maze will be just bigger).
But I get, that it was made in 48 h, so it's fine.
