And this, children, is why you should never play baseball.
Late one night, a young boy named Mark is making his way home after a ball game, when he suddenly spies a strange star shining in the sky. Little does he know that the star is actually a monster from a distant world. The monster nonchalantly crashes in front of Mark and introduces himself as Bert. Bert’s world has been overrun by evil monsters, and the only one who can stop this threat is the literal first person Bert asked. And by “asked” I do mean forcefully drafted into the skeleton war, as Bert grabs Mark by the hand and flies away. But perhaps with the combined powers of Bert and this child with a baseball bat, this world of monsters can be saved.
Welcome to Monster Party! This is an NES game and an early example of a boss-centric game with levels interspersed between them because it would probably weird kids out if they were absent. You play as Mark, with an attack-reflecting bat. Sometimes, he becomes Bert when he takes a pill, and Bert can fly and shoot projectiles. The two playstyles are actually pretty distinct, so how you progress through a stage depends on how recently a pill has dropped.
Spoiler policy: extremely do not spoil anything ahead of time. This might seem strange for a niche NES game, but Monster Party lives and breathes by the weird shit it throws at the player.
