Despite what the tags say, it's not a metroidvania, it's closer to a classical castlevania / megaman game.

That said, it's a short fun game with local co-op. I specially reccomend playing with a friend this way.

I really wanted to like this game because I like Gal*Gun and thought Bloodstained Curse of the Moon 1 and 2 were great. 2 less so for its unforgiving difficulty. What we have here is an uninspired spinoff that takes elements from Bloodstained and a little bit of Gal*Gun and we get a game that can't decide what it wants to be. Gal Guardians has the aesthetics of a Metroidvania, but with none of the fun of exploration of one. Some of the dullest and most forgettable music I've ever heard in a game. And really lousy boss design compared to Inti Creates' previous efforts.

There are far better Castlevania-likes out there, don't waste your time with this.
