I'm a bit curious where you found some of these tricks, I have been a speedrunner of this game for a few years now and there were multiple tricks that you did in quite different ways than you would in a speedrun (one example being the elevator which we just spam instead of timing). Very cool video and cool to see these tricks shown off like this!
Actually hated playing this game but really liked all of the out of bounds shenanigans you could do. Never did find all the Easter eggs when I played tho
