Literally unplayable. Seems like this issue has been around since launch based on the threads I've found trying to troubleshoot this. Following the developers troubleshooting steps didn't help for any of us.

This should really be tagged with Local Co-op and Local Multi-player. Luckily I got this through humble bundle but was very disappointed after installing trying to play with a friend.

To be fair reading the full description it is mentioned, but steam does have the specific tags for it which would make it much easier to spot.
