Silly question: did you unzip the game first?
Also does this error pop up on every object created or just a certain one?
It doesn't appear anything in buildmode to build.
So basically I press b (buildmode) then i press 'e' or 'q', the program stops. (Sand_Alpha.exe is not responding)
The good thing that the song(Audio of the game) is still plays somehow when the program is stop
(Btw I used to play your game before 2 years, it was my fav game, thanks for the game that got me through lockdown:)
