It’s Where’s Wally? on hard mode! Level after level with minute characters and things hidden behind other things and the occasional puzzle, where you have to find stuff from a list with sometime cryptic clues as to where they might be. Click on everything just in case!
It might sound easy, because Where’s Wally? is easy (and the Mega Drive game based on it is probably the easiest game I’ve ever played), but this is not. Things aren’t static like in the books either, so sometimes you’re hunting a moving target.
It’s a pretty big game, with the version I have including several extra levels over the original release. Only bad thing I have to say about it, is it made my laptop run incredibly hot for some reason.
