A platformer, with a comedy twist!
That's what truly sets the game apart, it's oddities, how many other games do you play a small slug like creature or piece of sewage, I'm not sure which, desperately trying to escape the confines of an underground sewer system before the flood waters catch you?
I never actually owned Flood, just spent many hours on my friends machine, wishing I owned an Amiga of my own.
Excellent fun!
