How to play coop? I invited my friend but cant play together.... I get a message `Coudn`t find server`

I have few questions about achievements in game >< 1) Beating the game without breaking the glass. Does it really work the way I think it does? You just have to go through the game with no checkpoints without ever pressing R? Then how 10% of players do that? (maybe its about some section of the game?) 2) About "break the glass 500 times". The window is only counted as broken after PRESS R TO RESTART pops up on the screen, if you press R before this entry, even if the glass is broken, it is not counted in ...

A random crashing the game around after 5-10 minutes: The UE-GlassCarrier Game has crashed and will... Fatal error! any tips to avoid this?

Before I buy, does this have an option to invert the mouse? I can't play without it.

При запуске пишет ошибку, мол не установлены дополнительные библиотеки Visual C++, прошу разработчиков врезать в игру дополнительные пакеты установки как в других играх. Буду признателен....
