This is apparently something that people do now (spoilers, obviously):
Source code of my contribution to Cragne Manor
I don’t really think this is of interest to anyone but me, but to me it is rather interesting, as it is my only work of interactive fiction.
It contains one very frustrating bug which made it into the final game: When the player enters the greenhouse, a timer starts ticking which makes scary stuff happen. However, this timer isn’t paused if the player leaves the greenhouse region, and it isn’t restarted if the player returns. When programming it, I simply didn’t consider the possibility that the player would leave the greenhouse and return later.
So in practice, pretty much all players entered the greenhouse, got the hint that the puzzle here couldn’t be solved yet, left in order to come back later, and never saw most of the stuff that I spent so much time writing and implementing.
There are other pretty bad bugs, such as the player dropping all supposedly un-droppable things when hitting the ground, but at least this was fixed by Ryan and Jenni before the release.
EDIT: After looking more closely at the source, the above seems to be incorrect. There is no timer, so I don’t know why things are not being triggered in the release version.
