Thank you so much! I'm working on a rewrite with some extra features. Hope to use that as the engine for a future game as well. I appreciate your comments!
Yes, potentially! I am working on a rewrite right now, it should make the Android version easier to maintain and a lot smoother. At that point I'll look into publishing it to other storefronts.
I see a lot of people have already given this feedback, but I'd love for the editor to have some sort of practice mode feature. That way, custom remixes can all have their own tutorial which would make it WAY easier for newcomers to understand how to play.
