A few notes on the visuals: I love the lighting, the water effects, and the zoomed-out perspective, especially when it comes to solving large, multi-step puzzles. Which, as far as I can tell, is exactly what one does in Vessel: nano-machines called fluros suck up liquids -- water, lava, oils -- and retain their characteristics, which our unnamed engineer will use in a series of Rube Goldberg machines.
The result seems like a cross between the Incredible Machine games and Oddworld: Abe's Oddyssey, which may explain why Vessel was nominated for a Technical Excellence award at the 2010 Independent Games Festival.
Vessel is slated for a winter release on Xbox Live Arcade, PlayStation Network, and PC, but will be playable this weekend at PAX.
