The heck is going on here?

When I fire up the game with my steamlink, the video only displays on my computer monitor, not on the Steamlink. Other games do not suffer in this way. Help! I think my wife might actually play this one with me! (Audio and Controls do pass to the Steamlink as expected)...

Title basically. Bought cause the store said multiplayer and co-op so i assumed there was online game play too.

Hello, It seems like I can only play with a second controller, I only have one. I want to play the Corgi with controller and another character with keyboard. Is this possible? Also the game runs a bit slowly when I'm lauching it (4-5 minutes until I reach the game menu) even with latest drivers. I'm on Windows 7, dual core 3.06GHz, 4GB RAM, Nvidia GT 310 afterwards it plays good. One last thing, it doesn't seem possible to take sceenshots with F12, any solution? Thanks for help...

The ingame tutorial tells me to either press 'up' on the keyboard or 'x' on my controller to jump. Neither of those work. I did, however, discover that the escape key and start button make the corgi jump. I don't even... :S
