Fatal Hearts calls itself a “visual novel adventure”: a kind of relative of IF which involves huge amounts of character dialogue (largely uninteractive), interspersed with set choices (go to the mall, or do your homework?) and puzzles (such as Theseus-and-the-Minotaur-style maze escapes to see whether you get away from your pursuers). It belongs (as far as I can tell) to a tradition of Japanese adventure games and the sort of thing done in Ren’Py (though Fatal Hearts is not itself a Ren’Py game). Play This Thing! reviewed it a short time ago, and I’ve been curious since.
