Sometimes a 2 and a 4 are colided togher.Sorry for the typo

Ahhh much better! But sometimes it fails to create a new tile after you move. The UI is also quite slow. The ratio of 4s to 2s that get spawned seems off. 4s are spawned far too much; you often get a 2 and have to wait 5-6 turns before you get another.

It seems to be unplayable to me. Any time I press "up" the game starts playing itself, sending the tiles up automatically and ignoring any other inputs. Perhaps you're so used to stacking along the bottom that you never pressed up while testing the logic.

Sometimes the blocks spawn inside eachother, but really good game!

Sometimes high score doesn't get uploaded to scoreboard. It happened to me couple of times already. I posted a photo so you can check it
