Yeah sorry i wasn't able to build the game so i made an empty page while downloading another engine version !
The game files are now published :D !
I'm fairly sure this wasn't intended, but I could not turn around fully, basically I could only turn as long as my mouse met the edge of my screen
Oh yeah i just saw that ! To lock the cursor you need to unfocus the game then re-click on it !
That' s very weird, but it did work haha
