This particular GameDev.Net forum thread is rather interesting, as the poster is advertising to fill two programmer positions for a 2D action-puzzle game called Skymning. Note the team structure (Primary design is being handled by Nicklas Nygren) and previous work by team sections (Nicklas Nygren, Director/Lead Artist - Knytt Stories, Knytt, Within A Deep Forest).

Apparently the game has been in production for over six months, and will be released on the PC, Wii and "possibly" Xbox 360 when completed.
