Thanks! As for tutorials, we do think that they should always be in any game, and not as just a text window in some menu, but as part of the gameplay. We just didn't have the time to implement it, unfortunately. So right now if you don't understand the controls or what's going on at all and what you should do - read the description on the game's page. There is a 'how to play' button in the menu, but it's partly a joke aimed at fellow Unity developers, so if you're not familiar with Unity, it could probably be confusing.
