Ok, android can play. I can confirm.
In this website. But...
Umm keyboard doesn't appear to write text lol???
I use web browser puffin since it does have keyboard options trigger but it's not save progress i think??
Save games haven't worked in WebGL since a browser change a few years ago. As for Android/mobile use, I can't provide any particular support, it is what it is. The Windows version is the primary target build, WebGL should be considered as a demo.
i guess at least it let me try game lol
