This is a fantastic title. A real shame that back in the days we where missing two whole levels, but still. Level 2 is totally amazing, level 3 is very good too, but linear. I will not even mention "level 1" :picard: I will have to give a go to the fully completed game one day.
Yes, the second level is a whole game itself..I hate the first level. I'm not good for those puzzles..
