Makaimura for WonderSwan is the 4th game in the Ghosts 'n Goblins franchise. Developed by Capcom and published by Namco on the short-lived WonderSwan console, Namco's attempt at a handheld video game console.
The game stars Sir Arthur, trying to save Princess Prin-Prin. It is just about what you'd expect for a Ghosts 'n Goblins game. You fight a bunch of enemies by throwing projectiles, you are committed to horizontal jumps, and of course the difficulty is very high.
That doesn't stop enderpal7, who breezes through the two loops of this game in record time.
