That's unfortunate that the game developers did not get back to you. They should have at least given you a response. There is no excuse for that. The proper response from a Unity game developer who wants to sell a Linux version but not support it is pretty simple- just offer refunds for anyone who has problems. 0 work and problem solved. Also, good Unity developers know there are platform specific issues (and how to solve them). I'm not saying platform specific bugs don't exist. They're just rare. When they happen, post on the Unity forums or Unity Answers site. Unity employees will read it, and get back to you. The support is great. This is why you use Unity. Let Unity do this work for you!
