Eeeeey you got it! OR you might be the first person to actually confirm they got the super-er secret-er ending (which is different from the Super Secret ending) - unless Balla you got fed up with my lazy grammar and also found the super-er secret-er ending.
Many thanks everyone - I've had a lot of positive feedback, even though it is ultimately a stupid piece of crap! But yeah you're right, I should've thought of a funnier thing when the other chap gets locked in (it's a throwback to the original game jam version where closing and locking the door were two different states - but that kind of extreme hyper-realism just leads to too much crunch time, you know).
I've got the ideas for the next project, and am keen, but am having a break to actually play some games as well.
