That was a long time ago. Therefore, I will only talk about my childhood experiences. They may be at odds with the facts. One of my favorite games. A very interesting and unusual game mechanics. Adventure platformer (beet 'em up?) with RPG elements. You need to collect items and return to the passed locations to re-interact with the key characters. An impressive story. Exciting music. An unexpected ending. Amazing bosses and unexpected combat systems to fight them. A huge number of ninjas and other nimble villains continuosly fall in on the hero. And you have to treat them with a fist or a boot at such a speed, that your joy's buttons gets hot. It was cool and challenging in the 90s. Many fun!!!
