YMMV / Atlantis no Nazo

• Game-Breaker: About the only thing that gives a serious edge to the player in this game is the star, an Invincibility Power-Up that lasts until the player dies, even between levels. Doesn't protect the player against the abundant Bottomless Pits, but it still makes large chunks of the game (especially the brutal final screen) much, much easier to manage if you can keep a hold of it.
• It's Hard, So It Sucks!: The game is infamous for its difficulty, from the maze-like levels requiring guides, to an rather inefficient starter weapon, to enemies that kill you in one hit, with no continues either.
• Scrappy Weapon: The starting weapon, the bomb, which is slow to detonate and only one can be thrown at a time, making it hard to kill all but the slowest enemies. It's more efficient to simply avoid enemies.
