Looks really good i hope we get to see an android version
It is in my list of things to do, but at the moment I want to focus on making a quality experience.
Making .apks in unity isn't too hard, it just requires optimization. I am using Unity's 2018 2D animation package, and it's not very well optimized. Once I get an animator on board, I will get the animations done outside of unity and that should be enough to get it stable on android.
I have been making the UI with Android in mind though.
