Like the title says:

This is the launchupdate. From now on the game is (nearly) feature complete. Every feature, that will be added from now on are nice to haves,...bis one exception, but this will keep a secret until I have implemented it.

There are several improvements on the playability and UI, Bugfixes and an added tutorial. If you encounter any bugs, please tell me. Otherwise from now on it's more about adding content to the game for more replayability and a better game feel.
