Chelnov is a platform shoot 'em from Data East
The player controls a mutant character that is always running, and will only
stop running when he reaches the boss. There are power-ups that can make the
player shoot faster or some that increase the size of the weapon currently being
used (which also increases the damage it does). The player can also get
different weapons other than the beams he has by default. These include rings of
fire, boomerangs, rockets, a chain, and more.
