The Sexy Brutale. From the opening screen I knew this game would be my jam and yes, so much. Haven't finished it yet but the look, the story, the puzzles, the characters, the goddamn music! This might be in my top ten games of all time. Maybe even top five and I haven't even finished it.
It's a murder mystery style puzzle game but more howdunnit than whodunnit. It has a time mechanic and it's worth watching through scenes a few times before trying to solve it. Bonus, it's Steam summer sales and a third off at the moment.
