Well, this is what I get for not checking supported platforms before actually purchasing a game. I saw this game listed on Desura, which I run on Ubuntu. Only Linux games should be listed and the summary page indeed says that the game has a Linux version. I bought the game but when I attempted to install it, it claimed there were no available releases to install. I checked the summary page again, it still says it supports Linux but this time, I notice that the 'Buy' button doesn't have a Tux icon next to it.
