Playing on Linux + Firefox, web version.
The mouse controls just don't work. If the Unity window has control of the mouse, it looks straight up and jitters wildly. The only way to actually look around is to have control held by anything besides the Unity window (like, just Firefox itself) and pirate-ship style sweep from the left side of the Unity window to the right, in order to move the view in that direction.
This looks pretty great; you have the aesthetic of the Backrooms, and I want to see this do well! :D
