There is a version in the google play store. That version is HERE. It doesn't run especially well, which is why I am in the process of switching engines to Game Maker. An Alpha Version of that Demo is available on my web site https://andrewhigginsdesign.com/quantum/. It is VERRY much not done yet (which is why it is not posted here), but it will give you an idea of what I have been up to for the past six months.
Thanks for the Follow! Let me know if you have any other questions.
