The game is now out - wohoo! We've done our best to make the game as good as we can and the current build is very much final. The last thing we did after the "update beta" yesterday was an improvement for the second tutorial where you need to break the wall - it should be quite hard to miss now.
We'll try to fix any problems which remained hidden as quickly as possible.
Anyways, enjoy the game! You can leave us feedback on the forums or via the feedback button in the game!
