Ages ago, I played a graphical adventure game called Mr Pumpkin Adventure. It was good, but very, very bizarre. Isoland is by the same guy and is also very bizarre, although perhaps not quite so much.
You begin on an island, and although it seems your job might be to figure out where everyone has gone, in fact you mainly just discover the presence of aliens, and find clues and items to crack codes to open areas or activate things.
Like Mr Pumpkin Adventure, it’s pretty short – but once you complete Isoland you don’t get the full story, and have to run through it again in what is essentially hard mode, with more puzzles. It’s a nice little game.
