Decided to post a photo to hopefully make it clear what's happening.
If I try to select the block with the red cross (for example,) the game is selecting the one where the orange arrow is pointing. Happens on all surfaces. It's like the view is off kilter or something.
Just for clarity:
Beta version of the game was working fine apart from crashing when closed. (known bug)
Removed myself from the beta program and had to uninstall the game
New version of the game was bugged as above
Uninstalled, restarted my tablet and installed it again
Game still bugged so played with settings, deleted a few things on my tablet and checked Android is up to date.
Game was still bugged and is currently unplayable.
I've just seen there's an update on the store. I'm going to give that a try.
It looks to me like "split controls" somehow got enabled in the settings, have you tried disabling it? To do that, go to the controls section of the settings menu and press "Touch". In that area there should be an option called "split controls" that you press to disable. Hopefully this helps! Here's a screenshot of it:
