I love your game! If you ever make a 128k version and want music I could provide some, just get in touch.
Thank you very much LeeBee, I hope you enjoy it. I am not planning to make a 128k version at the moment, because, although I think that music is a very important part of video games, and I always pay the most attention to it, composing or adapting it myself in most cases, this game asked for silence, and I like to only hear the sound of the pieces as if it were a chess tournament. On the other hand, everyone can choose their favorite music to listen to while solving the challenges.
However, I appreciate your offer and I will keep it in mind if I finally make an extended version in 128k. Greetings!
