One thing the developer did forget to disclose was the expected minimum system requirements to run the game (at least I haven't been able to find them anywhere), so there's a good chance when the game is instantly crashing. the people trying to run it probably don't have a computer strong enough to run it.
I can disclose my specs here if the developer would like to start making a database of computers that can or can't run the game (it runs fine on my system), but only if the developer is going to respond & actually make it a point to use the information that is being given to him to estimated system specs necessary to run it. Simply pinning a new thread to the top of these forums would also be acceptable, people can give there system specs there & disclose how the game runs on their system.
