Shadow of the Ninja

Shadow of the Ninja can be played by up to two players simultaneously, with one player controlling Hayate (the male ninja) and the other as Kaede (the female ninja). In either mode, the player can decide which character they want to control before the game actually begins. There are no actual performance differences between either character.
The player character can run, crouch, climb ladders, attack, and jump like in most side-scrolling action games as well as hang onto an overhang and move under it. If the player has more than half of their vitality remaining, they can perform a special attack by holding a button for an extended period, summononing a thunderstorm that will damage all on-screen enemies, but at the cost of roughly half of their maximum vitality.
The player’s default weapon is a katana, which can be traded for a kusarigama and vice-versa. The kusarigama has a longer range than the katana and can be swung upwards diagonally and horizontally. However, the kusarigama can only damage enemies from a specific distance and does not work as well at close range like the katana. If the player picks up a weapon they already have, its attack power will be strengthen by an increment of one level (with up to three attack levels). However, if the player takes too much damage, their weapon’s strength will be reduced back to its previous level. There is also the possibility to use both weapons, if the player starts with the kusarigama and collects secret powerups hidden in some levels (for example in the central wheel of level 1.3). The player can also obtain shurikens and hand grenades as well, both which can only be used as long the player’s supply lasts before the player reverts back to using the katana or kusarigama. All four weapons are obtained by destroying item boxes scattered throughout each stage, along with vitality potions. Something worth mentioning is the fact that the potions being offered in order to heal yourself if played by 2 players will have different colors, which depending if the color of the potion is the same as the character that use it, it will replenish a large amount of health but if the color of the potion is not the same it will heal less.
The game consists of five stages, with the first four stages being divided into three segments and the final stage into two. The player will fight numerous types of enemy characters throughout each stage, including bosses and sub-bosses. once a boss has been defeated it will explode, this explosion will heal players the closer they are from it, since actually the same amount of health from one stage will be carried to the next one until either recovered with potions or by dying. The game ends if the player loses all of their vitality and only five chances are provided to continue. If two players are playing the game, their continues will be shared.
