(p.s. I think playing this on phone would make it easier to move and click the spheres, cuz you have two fingers and no need to move a mouse.)
Right now the web version should be fully playable on Android based phones and tablets, as far as I've seen.
I tried to get the web version to run on iOS based devices, but the export was buggy and crashed often, and afterward I read it's generally not recommended to attempt running web exports on iOS.
As for a native mobile version, I couldn't release it on any iOS device, since explicit adult content is not allowed. As for an android version, I have no plans (since I don't own an android device to even be able to test it), but I might consider it for future games.
