2nd multiplayer update

Hi all,

In this update, four more characters move into the Escape Room. Well, they are not living there... but you can choose one of them for the multiplayer part. I would like to make this collection of heroes a bit more diverse so if you know any good 3d models in a similar style (but also cheap) you want to see and play in the game, let me know.

On top of that, South America and Russia are now available as server regions where you can gather around. The needed data rate for playing multiplayer was lowered a bit to support the users with lower bandwidth.

Last not least like always there are a few tiny adjustments based on feedback to make the game more clear and more bug-free.
