Vessel, has been released.
Nominated for an IGF award in Technical Excellence -- which is an award we win daily -- Vessel is available both on Steam and via the developer's own site.
To sweeten the watery deal, Vessel is available for 10% off its regular price. Purchasing the game from the developer will net you a DRM-free version and a Steam code. The promotion, which drops the game down to $13.49 from its original asking price of $15, ends on March 8. Act fast because ... uh, something, something sink or swim? Vessel is liquid-based, so the joke holds water.
