i'm not sure what cars you mean, are you referring to the digging machines? they are just for decoration. i have not seen that bug and it's a very strange one, i don't plan to work on this any further but i'll still be taking a look to see what that was, so thank you for letting me know. i agree about music but i just couldn't decide on anything in time. the music from the trailer was one of my options but just didn't feel like it fit the game while i was testing it. there have been a lot of comments on that rock so i will definitely be watching out for that in future games, but i was kind of aware that sticking progression behind a technically hidden wall might be an issue which is why it's in the trailer (that's not a good way to handle that, but i also didn't expect it to be an issue with so many people. lesson learned). thank you for playing though and i appreciate the feedback!
