Love the series. I've been playing them since I was 5 or 6 (so some time ago
). The only part of the series that I don't like is the one with the Dreams full of vegetables and such things that are totally not Keen-style. Otherwise I give this game 5/5 - wonderful graphics, nice storyline (for a side-scrolling game that is
), very very few bugs, great variety of enemies and levels.
Can't imagine the history of gaming without this jewel. I would love to see another part of the series with the same engine, hero etc. Dunno if the engine is opened now (id software's policy is to do that when a new engine comes out).
