Hey,
just tried the game and really lost myself in building roads and houses for a couple of minutes and the game crashed without throwing any errors, just closed itself.
As I read in the other review(s) IF it happens it does so early on.
Have a look at your variables, maybe one is trapped in a while()-loop that gets triggered for some players that do certain actions
I crashed EXACTLY (frame perfect!) as I completed the last click of building a road that (with this last click) would be connected back to its tail, that's very suspicious so you might have a clue there
Looking forward to your progress!
Best regards!
