Not too little and not too much. Very memorable and very re-playable. Fun and creative but still classic side-scroller. I really like every like every element of the game. The character sprites, helpers, obstacles, even down to the level design and backround. If it was on the NES it would have been as popular as bubble bobble or jackle, and then eventually be corrupted by corporate interests, have a million sequels/prequels, warfare of duty FPS remake, what have i done? hang self in hotel closet, RIP Robbin Williams.
