The first official Android app will be released together with the PC/Linux/MacOS versions on the upcoming update. The Android version you played is an unofficial port I am not affiliated with.
Happy to hear you liked the game!
I understand, I thought it was some paid version. Dude, why don't you publish a light version on the play store when the Android version is released? a VN br developer did this on the play store. He only censored sexual words and the +18 image. He got a big audience. Your game is very good, I think it would attract more people.
