Thank you!

Hello dear community,
We're nearing the end of our launch week and we want to thank you all so much for your support and for playing our game. It's fabulous to see what a great start MarZ has made and what we've achieved as a wife and husband team.The release was very exciting and exhausting at the same time, but we couldn't be happier now.
Thank! You! So! Much!
It's great to see that you are enjoying our game as much as we did making it.
It's awesome that the workshop is already growing very well and offers some very nice and creative maps to you to play.

As game development is quite complex and we gained hundreds of new players, some bugs appeared as well. Please bear with us that as a team of two it's nearly impossible to test every single aspect of a game. We worked really hard during this week to push several patches out which fixed the critical bugs. So please make sure to update the game via your Steam client.

We're really overwhelmed about all your support, comments, feedback and suggestions. Keep them coming! :)
Miriam + Marc
