But why do developers make games mostly made for controllers? Look I am not trying to bring this down or controllers at all I am just wondering?

I was literally turned off from buying this game at the last moment after reading that there is no multiplayer online. There is no reason not to have it. Even if you believe that couch coop is the way this game is mostly meant to be played (which is respectable), still you have to offer a multiplayer option to those who dont have "couch-mates". Trine, and Trine 2 is a perfect example on how a game with some ( and i mean "some") similar game mechanics would work over online mutiplayer. I played those games ...

Really like this game but one thing is bugging me is the scrolling seems to be a bit jerky and not nice and smooth. I mean it scrolls them jumps as if it is trying to catch up. Tried forcing v-sync but still the same.

Been playing this on PS4 its great, would love to buy it on Linux/SteamOS and get my friends to buy it too

can anyone help. and don't say use a Xbox controller
