Well, I finally figured out how to get Ren'Py to Android builds and it looks like it's functional and stable... so have at it!

For any aspiring devs out there with a visual novel slant, I'll take a moment to recommend Ren'Py in the strongest terms. It's user friendly, has been optimised for purpose for years and it has a ton of functionalities I'm probably taking completely for granted. (Also, it's free!).
