When I was younger, I used to play this game a lot. I can;t remember my exact methods completely, but I'll try to piece it together as much as I can.
At one point, when you were the fish, you would be (obviously) in the water. There was also 1 single shark, and a bottomless pit that, much like ones you'd find on land, falling into it would kill you - but you were a fish! You could swim over it!
I would get an error screen whenever I would swim down the pit with the shark following behind me, till the shark was also in the hole, preventing my escape.
I am a video game programmer, and I just want to know why this crash would happen? Theres no horrible error, just me cornering myself - but it's not outside game logic.
