Sci-fi puzzle platformer Transmogrify from Odyssey Entertainment has you turning aliens into useful objects to help solve puzzles. It sounds interesting and it's crowdfunding on Kickstarter right now.
One I missed actually getting full Linux support earlier this year was PLAY WITH ME, a game that mixes puzzles and horror together to create a weird experience.
Always on the look-out for new games, today I came across Algo Bot. A story-based puzzle game where you're trying to contain a crisis on a colonization ship. It looks like quite a treat for fans of puzzle games, especially since it pulls in aspects of programming.
CROSSNIQ+ is the followup to the free puzzle game CROSSNIQ, it's a little like Bejeweled (or any other match-x game) mixed with a Rubik's cube. It's on Kickstarter with full Linux support just like the previous free game.
For those of you looking to fly across rooftops and solve puzzles in the dead of night, this new puzzle game may tickle your fancy. It was released earlier today with same-day Linux support and I have a few brief thoughts.
We Were Here Too is a very interesting puzzle game, one where you and a friend team up and walk through different rooms and solve puzzles together using your walkie-talkies.
