windows build crashes when I press E key… definitely not bug-free.

why no linux version :'-(

Unfortunately, the "go north" command is not supported.

Also, there's no way to undo a command (i.e. "shoot" -> cancel -> "go") and the game crashes if you enter something besides a number when presented with choices

That was a very unsatisfying ending. Alternatively, that wasn't the ending at all, just a wall of text without a single link to progress.

Elevator buttons, the bane of ghost stories.

the game says "stylesheet is null" and the text is all black on black

Garry's Mod (and mods) and Source Engine SDK (you have it on Steam if you have any Source engine) would be more fitting.

Fixed. Note that the map is rather fiddly right now - you have to be sure you're clicking what you're clicking (don't click the text, click the points)
