Your opening sentence about the side-scrolling shoot-em-up is a bit confusing, since the game you're reviewing is a vertical shooter. The next sentence also needs to be cleaned up, because it got too complex for its own good and that led to some grammatical issues. Otherwise, though, the writing throughout was quite solid on a technical level. Your tagline promises the game is the greatest shooter ever made, and while your review didn't convince me of that (a lot of the best shooters are made excellent by the very things your text ridicules), you did make me head to GOG to ensure I had the free game in my library. I apparently already did. Or at any rate, I do now. I like vertical shooters, so I might someday even play it! In any event, it's clear you like the game a lot, and your review outlines the reasons for that without becoming dull in the process, so I consider it a success.

"What if everything you see is more than what you see--the person next to you is a warrior and the space that appears empty is a secret door to another world? What if something appears that shouldn't? You either dismiss it, or you accept that there is much more to the world than you think. Perhaps it really is a doorway, and if you choose to go inside, you'll find many unexpected things." - Shigeru Miyamoto on secret doors to another world
