Thanks for the comment! The ROM here is just a demo of the full game, which will be published by Mega Cat Studios later this year.
We have preorders up on Kickstarter right now (https://www.kickstarter.com/projects/megacatstudios/kudzu-a-brand-new-game-for-t... ) and we're looking at the end of the year for general availability on the Mega Cat website.
