Great questions!
So, all of my games are in development. I'm working on each one in blocks. I have a core set up per game. So, when i update one theme of the same game, all get updated. So there will be future development for the foreseeable future. There's a lot I want to add, so it won't be complete until I'm happy!
Yes, if you buy a game, it come with all future updates! I think bundles also include that.
So, I only added android at the request of a couple of players. I didn't even know if I was able to. That being said, I have set up the core loading and saving (which was the main problem at the start) to change depending on the device being played. So, all of my updates should be 100% compatible with android. The only problem I'm having is getting the videos to play correctly, so those are disabled for now. Actively looking for a proper way to fix it.
Anymore questions let me know!!
