Blue spotted this first-person puzzler over the weekend. Attractio reminds me of... something. I can't quite put my finger on it. Perhaps take a look at the trailer below and see if you can help me out with the association. Also, as Blue noticed, you can get at a demo if you fill in a survey. So that might be even more help.
Ah, I'm just being facetious. I'm glad there we're finally getting more first-person puzzlers. They will always be a fascinating genre, even if they don't fall too far from the portal. I like that the developers are called "GameCoder", too. No messing about with that name.
The game is due in the summer.
