I've been thinking about it, and not sure it would pass Steam certification. But I will see and ask around!
Personally I suggest for devs to not put on steam, with the current price and amount of Content, the game would go into the category of games that has a higher price compared to amount of content, and because the game can be beat in aproximately an Hour, it would go under the games on steams that can easily be refunded. So steam wouldnt be an easy market for this game, unless the price was significantly lowered.
