I think the achievement, "Unconventional Oven," may be bugged. I'm heating up EVE's core in the cafe's oven (assuming there isn't another way to do this).

So far, I haven't figured out how to exit the game or otherwise save or pause it without completing an ending (dying seems to restart it, as does F12). So far it looks like just LEFT RIGHT, SPACE/ENTER, and F function. (UP and DOWN for keypad entry). Otherwise, N and M bring up behind-the-scenes details like Eric's Templar class and Crossbow icon for the Pistol. Am I missing an obvious command to stop the game, because I can't even ALT-TAB out or end it without closing the whole window....
