Hi,
this is the Cyberhead team. We're ready to announce the start of signups for testing.
Now, on the Steam page there is a button to sign up for testing. Click it and don't be shy. As soon as the demo version build is ready we will invite you for testing.
You will be one of the first who will be able to evaluate the updated version, give feedback and influence the development progress with your feedback.
We are waiting for your requests!
