Great concept, and a lot of things can be done with it. For me, instead of being a logic game, it was actually a waiting game, bacause the walls often didn't seperate me from the exit, so I think a pre-generated maze would have been better.
thanks for the review, we came out this concept and made it in two days, so a lot of things need to be polished. Now the walls were just randomly generated, and pre-generated maze seems like a good idea.
