I don't plan to sell it on other platforms currently, but I will think about whether I can sell a full version on itch. The new version I am setting up with steam leaderboards, achievements, cloud save, potentially multiplayer with steam features, etc. I also programatically generated about 200 leaderboards to allow people to pick different modes/mods to play with and still have leaderboards if they want to challenge their friends on specific settings for steam, I also hope to allow people to see scores among their steam friends.
