Have you managed to fully download it, or are you getting any messages during the process?
If you have, what happens when you click the SpaceCorpsXXX(v0.3.4a).exe?
I always fully download the game but then it says failed due to network error
Hmmm... Doesn't sound like it's to do with the game then - must be your network, perhaps adult content settings or local laws?
PS: Merry Xmas! 🎄
