Shinobi, which you can jump up and down between at your leisure. Coming from both directions (and onto both tiers) are the many enemies who include default thugs in various coloured outfits, several types of martial-arts guys, wall-climbing buffoons, porky (and strong) wrestlers, and others armed with bombs, flame-throwers, and long grabby metallic arms. There are also middle and end-of-stage bosses but their toughness is a little inconsistent. For example, the first and second such guardians are a right pain in the arse (see Mr. Scythe Arms, above) and cost me numerous lives each, but the examples on the third and fourth stages can be bested with barely a drop of sweat spilled. That said, you still can't afford too many mistakes as their energy drops much slower than your own, so they take a while to put down, whether easy or hard.
RKS Score: 5/10
