Yeah, what ojh.games said, tetris-like predictions would help. I was thinking also that the rotations should be at most 90 degrees, so that it shouldn't go the right way and then immediately back;)
Also the controls are a bit clunky... Probably direct rotation with a mouse/analog stick would make the game too easy... How about a acceleration? When You press A/D i accelerates the maze in that direction? Because the problem I had was that it is too slow to operate, and sometimes I couldn't do anything because when I rotated the maze, the box was already facing the other way:D
Also I don't know if red fields were necessary... Maybe some other mechanic would work better, like speeding up fields? Or spinning, or teleporting, or an item that lets the box go forward for a longer time?
Overall, nice game
