Hello, thank you for reporting the issue! This is very weird, I just tried launching it on Firefox on an Android phone and it run fine. Perhaps it is some kind of issue with the mobile version of Firefox happening on certain devices, but I'm not sure why. We'll definitely keep this issue in mind though.
Thank you for the kind words as well, and we have plans on making an Android version sometime but it's not yet sure when, because right now we're focusing on improving the desktop and web versions a bit more, before having another version to maintain. But it will definitely happen some day, so stay tuned!
