Had a total blast with this as a child. It's actually incredible, but poorly optimised in such a way that you can't place enough items/characters before you run out of memory.

Hours were spent on this game in my childhood and my beautiful creations were all destroyed when the family computer's hard drive got reformatted. Farewell, "Homer Swims in Lava" and "Bartman Defeats The Aliens".

By the way, whatever you create in this program will be funnier and better animated than a current episode of The Simpsons.
