Dan I really think you need someone to help you. You've gotten this far and every day I see someone new on the forums. Soon people are going to start requesting things and you won't be able to answer them. In another post someone mentioned they are a game programmer. I think you need to take advantage of situations like this. You can't stay solo forever because soon there will be 1000 people giving feedback. BTW how many people bought Universe Sandbox? Can we get some statistics?
