(Take two...)

Better name needed.

Poster A posts a boss fight (or how it works or something), keeps it brief (500 characters max). It can be one that exists (add the boss's name and work (in bold)) or completely original.

Poster B posts what they think of it (watching videos on existing bosses is allowed). Then it's their turn.

An alien with a giant mechanical gunship armed with lasers, bombs, and other Bullet Hell goodies. While you get nothing but a little toy plane, maybe carrying Shurikens and maybe other ranged sub-weapons.
(Palenque - La-Mulana)

Regarding Palenque, it's got great music in both versions of La-Mulana. I like the original's colour palette and it's pillars gimmick but think that the remake has the better fight due to the Gradius styled bullets.
