After seeing the enthusiasm caused by the megafucking awesome Crimzon Clover and how the thread reached 16+ pages (probably the first doujin ever reaching SO FAST that amount of posts without taking into account western efforts like N.G.Dev stuff and a couple others), this is for you, the STG thirsty people, PC doujin supporters, fellow schmukmuppers, whatever. I present you ring^-27.
How can I describe this? Well, it's like Crimzon Clover meets Hellsinker in ultra low-res (and I mean, really, really low res). Bullets everywhere, numbers everywhere, items everywhere, pew pew, big bosses and cool enemies, less guided laser missiles and more of an "anchor" secondary weapon that sticks to an enemy for even more points, items and massive explosions/cancellations and extra firepower.
Actually, disregard that. I always try to find a way of comparing the games to explain things easier. Just go, download the latest version and try it. I find it hard to explain in english what this game is other than "fucking awesome" in caps.
And, no, quit asking. You can't TATE this.

It appears that the game was initially introduced during Comiket 78. It was commissioned to Temperance Lance (the creators of Patriot Dark) who included it on the same disc as their test version of the upcoming shooter L.U.X. Needlessly to say this was one of the surprises of C78 and probably worth trolling their booth to get this.
Warning, sumishiro is using that atrocious Windows Live download service that runs out of bandwidth fast. Tread with care.
