That's good because I had planned the demo to take about an hour to complete!

I know what you mean about game timers too - Steam's timer frequently adds on hours to my game completion time because it's still on while I have to do other things.
Thanks for the feedback, and I'm glad you enjoyed it.
Also, if you encountered anything that you felt was crying out for a funny response / something you were disappointed by when you got a generic response, please post about it in this thread too. I'll try to make sure, as much as possible, that everything players felt really deserved a unique response actually gets one!
EDIT: I've added a poll to the dev blog to see if people thought that puzzle was too difficult - head over to

(We'll put an extra hint in the full game if people thought it was too hard.)
