Sega Genesis Collection - Ristar Passwords (PSP)

Greedy, an evil space pirate, has corrupted the kings of Valdi System's seven planets and enslaved the people who live there. The plea for a hero is answered by Ristar who uses his amazing extendable arms and courage to save Valdi from Greedy.

Controlling Ristar is fairly simple. He is unable to jump as high as most platformer protagonists do, but his jumps have a bit more hang time, meaning he stays in the air longer. By pressing the grab button, Ristar will stretch his hands forward, grabbing whatever is ahead of him. The player can make his hands go in any one of eight directions by combining the attack with any direction on the control pad, except downward while on the ground. When Ristar grabs an enemy, he will continue to hold it until the button is released, causing him to collide with the enemy and destroy them. He can also grab walls and obstacles this way and it is possible, albeit time-consuming, to climb walls by continually grabbing diagonally up a wall.

Ristar's health is shown as four stars in the upper-right corner of the screen. Taking damage removes one star. When all four are gone, the last star falls on Ristar's head and he loses a life. Stars can be found throughout the levels, which replenish his health. These and other items must be picked up manually with Ristar's attack. A gold star restores one hit point, while a blue star refills health completely. A tiny icon of Ristar adds an extra life to the total. (Wikipedia)
