Whoot! Apparently someone near me had the full game(got it on a vacation)! Anyways, he lent me the cd, and theres some stuff which wouldn't be in the demo.
----------------------------------
Commercial events!
Radioactive goop- constantly dripping green liquid that hurts you if you touch it
A different 'door' sprite(in addition to the usual purple one)
Boss
Button(event used with the boss)
A floating screen showing the boss's head(his eyes follow you)
The boss
Red suckers
Moving floating platforms-Apparently what Batteryman is holding onto in the loading pic(demo and commercial versions)
Suckertube type thing
Freddy and empty/full battery animations that go with him
----------------------
I think thats a list of all the events not in the demo, I might be missing some.
