Just posting on here, also. Took me a little time to get the hang of it, but I really enjoyed it. I've also updated the thumbnail to include your awesome cover art

Thanks to you for playing it and for making a gameplay video. Ultimately, as an author, I'm very happy that my games are played. This is more of a hobby than a business, and that's why my games are free. I'm already on the 4th for the Atari 2600. Umi Colors was the 3rd. I hope you can try the first two, "Invasion" and "Mazinger 85."❤️👾🕹️
