You can also see some objects that are hidden in the real game, but in the editor show up as pink squares. (This game was actually released two years before Animaniacs, which was delayed due to publishing problems). It was later re-used for another isometric game called Looney Tunes: Back in Action. But the walkthrough shows all maps in the full size! These maps were generated by the level editor we used.
I thought I could also share some more or less interesting trivia about the walkthrough and the development of the game. I found it on my hard drive the other day and though it deserves to be released as intended.
The game was however severely delayed, and the walkthrough was forgotten and never publicly released. When I worked on the GameBoy Advance title Animaniacs: Lights, Camera, Action! we also put together an official walkthrough for the game.
