1. it was made by Pigeonsoft
2. some dude called Rieks Warendorp Torringa seems to have published the game when it was released
3. the abbreviation has no meaning, it just sounded cool
Cool, didn't know that.I didn't either until a few days ago when I decided to check which conditions were to be met and what happened when they were met. Of course I knew about the password already and the logic behind the first letter that was replaced by a space to disable it.
It was a nice question to ask though, to see if there were any other (regular) participants of this thread who knew about it.

<biology class>
ATP = Adenosine triphosphate. The energy 'currency' or 'coin' of the cell, transfers energy from chemical bonds to endergonic (energy absorbing) reactions within the cell. Structurally, ATP consists of the adenine nucleotide (ribose sugar, adenine base, and phosphate group, PO4-2) plus two other phosphate groups.

I never had any basic chemistry class, so these are things I don't have knowledge of.
