How about a system where the expire key works on a time system -
somewhere in the exe (maybe several places) you store the total time
(encrypted) the user has run the game, and make it encrypt itself after
a number of hours, only to be unlocked by the next key available on the
web site - that way you could "rent" the game to people for a small
amount ; 24 hours of play for $5 or something. People only rent the game
for as long as it takes to finish it, testing it for 24 hours only costs
a few dollars, levels could be available free because they would be
encrypted, and only a working game could break them open.

So a small game download with the initial payment, plus any single
levels you want to try out, then an extra payment for more renting time,
and free levels as they are made available.

Effectively you could make most of the game engine code open sourced and
free, and only the decrypter would be distributed in the binary game
file, and the levels encrypted using this. The codec could even be open
source, just with the specific keys put into the executable when it is
built by the distributer.

But ! Of course people could make copies of the original file and use
the copies to get extra time. Oh well.
