I really liked the simplicity of your game. I think you should make it more polished, for example, by adding more animations instead of just having the piece teleport to the side. You could also animate the instructions at the beginning of the game. Overall, I liked it and I think if you add more smoothness to the game, it will be very satisfying to play.
Thank you so much for your comment. I'm taking it into account and already working on an update. Honestly, I didn't think anyone would play it, and I was planning to leave it as it was, but your comment has really encouraged me. Thank you for playing the game, and I'm glad you found it fun. When I have the update ready, I can let you know if you'd like to try it. :)
