Hello everyone,
I am just ensuring you will get note also here, we are releasing BLACKHOLE 1.11 hotfix for Windows - because of new season of Challenge Vault Online mode.

This is not affecting at all DRM-FREE version of the game. There are no changes in regards of bugfixes or new features.

Challenge Vault is online mode available only on Windows using specificaly only GALAXY. If you're not using Galaxy to run the game, you're ok. If you wanna beat some online times, you need update BLACKHOLE to 1.11.

So, right now the version scheme for GOG is:

Windows 1.11
macOS 1.10
Linux 1.10

We will update macOS also to 1.11 later this week with same hotfix - but Challenge Vault is not available on Mac platform right now - so please, bear with us.

Thank you very much for understanding.

Enjoy the game! :)
