open the game up in unity a day later and the game wont run.
i made no changes at all after building it. i even deleted ALL objects in the game and made a new camera with some basic movement controls and it wont move.
I had a similar issue once where Unity’s time scale was actually set to start at zero when I crashed it in-game in a timescale-changing function. Check your project settings, too, and make sure it’s set to start at non-zero.
