hey sorry to hear your having problems. I will take a look at it and see if i can rebuild it for a newer unity. do you have a dedicated GPU?
Im not sure what i could do given those specs. Even if it did run i dont think it would run well. I recomend getting a desktop if you have the space for it. Much more power for the money and more upgradable so it will last longer.
I will make a version of the game that uses a diffrent renderer tomorrow. It wont look as good but it may run.
