I'm surprised I haven't reviewed this game yet.
This game is a masterpiece, when a game says it's got overwhelmingly good reviews, it's probably cause it's really good.
Everything about this game ranging from its story, gameplay style, music (the music is definitely one of the best OSTs out there. It's a super neat "Run and Gun" metroid-vania type of retro shooter, definitely with its own easy and challenging features, when the game gets too easy for you there are a couple other modes that will keep you busy (especially hard mode, I haven't beaten it yet, and it looks like a nightmare).

The story is nice and linear in the worlds you travel to but then you can also travel back and forth and collect secrets, and there are 3 different endings to this game, so some choices can make a difference.

Even if it is a masterpiece, there is one little thing that might get annoying around the third playthrough or so, is that through the story there is a lot of going back and forth to collect items for this that, but I guess that's just a big part about how you're supposed to progress so I can't really complain much about that.
This game is as good as it gets if you like retro platformers.

The shooting mechanics have to be my favourite, every gun apart from the rocket launcher has no cooldown so it's very satisfying to mow down bosses by jitterclicking, it's very trigger-happy friendly, and again, all guns except the rocket launcher doesn't actually use any ammunition either, so, yeah, even the shooting is skill based.

I am going through my third playthrough (after accidentally losing my save data for my second run and almost beating Ballos, because I reset my laptop without a backup).

This game doesn't need a very good computer to run, it's not very demanding in terms of RAM either.

I love the music, please play this game, it's worth your time, 100% (unless you don't like platformers, then that's okay).
