I was playing the 2048 game and the image of the 4096 block is not visible. It stays at 2048.

Below a good image which shows I can't be 'game over' in this setup.

Could be wrong, but I don't think there is a 4096 tile in Subeta's version of this game, so this isn't a bug.

A real shame though, Higher scores are possible in some versions of 2048. Would be great to see that applied here.
