A&D reminded me greatly of Monty Python.
Though I only played the game because of the humor, the gameplay was horrid repetitive and unfair at times.
Hahah - cool - another person who played that game! I think I felt about the same way as you. Any game that has a shark gun comes out of the starting gate with a pretty good score from me, but the crazy guns and humor were the high points to balance out some of the frustrating gameplay bits.
Haha! I remember that gun, I loved using that gun and watching people get mauled to death by Land Sharks. My favorite gadget was the Topsy-Turvy Bomb, which didn't really help much, but sure as heck fun to watch the world turn upside down and everyone fall down(up?) and crash right back down.
