When we visited Southend Interactive a few weeks back to see Lode Runner and R-Type Dimensions they also hinted that they would announce something new soon. This game is Ilomilo, an original concept coming to PC, Playstation Network, Xbox Live Arcade and mobiles.
Southend received funding from the Nordic Game Program (€67,000) recently for the project, and they have opened a very secretive teaser site. But the company is still in pre-production and they don't expect to show more from the game until Game Developer's Conference in March.
