Keys of a GameSpace is a short Adventure Game Studio title that rather pretentiously labels itself an "expressive game;" a sort of artist's statement on the site explains that the game is an attempt to explore games' expressive potential and that "games are not a trivial medium of expression." Doubtless some would find this an impressive claim, though I expect most readers of PTT! would respond "well, duh."
But, as most readers of PTT! would also doubtless agree, what's important is the game, not any claims made for it. Keys of a GameSpace has merit.
It's a short game, with a walkthrough available on the site; at the beginning, the protagonist, Sébastien, is told by his girlfriend that she wants a baby, and he has a day to decide, or she is leaving him. From this, we transition to a blank space with three doors; visiting them, we explore Sébastien's past, and must solve a simple adventure-game style puzzle to unlock a fourth door, which transitions to another set of three.
The puzzles are not important here, except that the items used to unlock events have some metaphorical meaning. That is to say, don't expect deep and entertaining adventure-style puzzles here; Genvo's goal is to tell a story, with the unlock mechanics of the genre providing a mechanism for narrative reveals.
The story itself is somewhat disturbing, and emotionally impactful; and yes, it deals with the issue of pederasty, though in a tasteful fashion.
In full-screen DirectX mode, a bug sometimes makes it impossible to change the action cursor (which, as in most AGS titles, cycles with RMB). This unfortunately also makes it impossible to save progress at that point, which is annoying. It's advisable to run winsetup (supplied) and play in windowed mode using DirectDraw instead.
