A physics-heavy action game where three characters allow clever solutions to challenges created by hazardous puzzles and threatening enemies. Mechanics based on fully interactive physics -- each character's different abilities and tactics can be used to invent new ways to overcome obstacles and save the kingdom!
Some screens from the official site:
Teaser and trailer on GT.
So at first glance I'd say Hocus Pocus meets The Vikings, and then some.
Frozenbyte are the guys responsible for Shadowgrounds, a pretty decent top-down horde-mower. Sort of a modern day Alien Breed. I threw a couple of hours its way when it came out.
As for Trine, well it's clearly made in the typical Western idea of fantasy fashion. Meaning lots of the bloomy and the blingy strung all over the place. A bit too heavy on the eyes for me, but the game seems like good fun from the trailers. I just hope the neon crap can be disabled in the PC version.
