Huh, that’s very interesting, I’m very sorry you encountered that bug. And yeah sorry I should have made that more clear in the tutorial, which is my bad. I decided to try my best to clear up some ambiguities in the game’s description. Thank you for your feedback!
Edit: The slow camera movement has made me think, what kind of hardware are you playing on? I’m worried that maybe the game is running slow, and I forgot to multiply the camera movement by deltaTime, hence resulting in a slow camera. If it slow hardware that could also explain the crash.
