Thank you very much! I made the movement speed a bit too high to make it easy for the player to quickly collect all coins in the maze and get the maze-clear bonus, but yeah that made it hard to go through some of the paths in the middle with that high speed.
And yes, the mazes are procedurally generated, and the coins are placed where ever the algorithm stops at a dead end and has to traverse back. The entrance and exit on the top and bottom are just randomly placed however.
Thanks again for playing and for the feedback!
