Thank you very much for your note. Regarding the design of the stages, I had made them specifically to resemble a maze so that the game would be a little difficult. I tried hard to make the game have only two colors. There may be a color gradient, which is the blue color, but when I tried the game, I did not see more than two colors. As for the difficulty of the game It was very difficult at first and now it has become easier, but I don’t want you to imagine how extremely difficult it was at first. Designing the stages is the most difficult thing for me, but I tried to do the best thing as much as possible.
