I just finished playing a magnificent puzzle game. Gorgeous art, non-standard puzzles - the whole thing is one big puzzle, actually. I'm personally addicted to those Aha! moments in gaming and Gorogoa has several.
Since I can find no mention of it on this adventure game site, I thought I'd share here - something I've never done before.
The name of the game is Gorogoa and it can be bought ($12?) on the Steam website. It took me over five hours to complete but at least one hour was spent making maps of various connections and possibilities.
As the friend who gifted it to me said, "A puzzle lover can't NOT play this game." I agree.
