Wow! What a great game - I really enjoyed it. I love the concept and the sound when you match two colours together is satisfying to me. I think not having background music enhanced that and did well for the theme of minimalism. The only thing is, I think there's a possibility to make it so the player ends up making the puzzle unsolvable. I ended up getting stuck this first time around but the second time around I was able to finish in 36 moves! When I was stuck I got up to 100+ moves on one of the puzzles, so I wish there was a note for a recommended amount of moves the puzzle might take along with a reset button if you get yourself stuck. Overall I had a blast playing it, great work!
