Hello, I played your game and beat it. So, this game was not as enjoyable as it could have been, so let me make some suggestions. The essential gameplay loop is finding the right square. Right off the bat, there's no skill involved rather it goes down to guessing. Perhaps what you could have done is make the right square a different color, and the skill would have increased. You could even make it harder by making the color slightly off. Also, there's no sense of progression or score system, so the main reason you would play this game is internal motivation. Now, internal motivation is not a bad thing, in many cases it's a good thing. However, in this case, the gameplay loop might have not been engaging enough. What could have helped is adding more complexity. There could be maze structure you have to move around rather than free roam. There could be red enemies you could avoid though I can see how this one could have been frustrating. There could have even been a lock and key mechanic where different colored squares open (and even close) sections of the maze that help you (or even hinder you). Adding external motivation as well could also help.
