So I got the game on steam last night. It's hilarious and has a cool engine. It looks like it could have been made in flash though. It makes no sense why it took them so long to make. 90% of what makes the game great is the writing.
Since it's not a GPU buster, it feels a bit like an indie game, and paying $60 for it seems a bit steep for that reason. But don't get me wrong, it's super entertaining.
