the android version is almost unplayable, multiple issues from screen tearing, to having to play upside down, to UI issues, generally it seems st didn't test anything before uploading  or if he did he didn't test on multiple android devices.

I'm on a table and working fine for me 

Give them time, their just letting people test and figure out the bugs for them. Their still new to godot engine and so far windows doesn't have any problems. 

Thanks for the feedback, may I ask for more detail on the UI issues?

For the upside down problem, it will be fixed by disabling orientation lock in next update.

Also what phone are you playing it on?
