Background of Hellsinker

You've come this far but if you're not into shmups, you probably have no idea what Hellsinker is, do you? Don't worry!

Hellsinker's Background! Hellsinker is a shmup released in 2007 at Comiket 72 by Ruminant's Whisper. It had been in devlopment for presumably a few years prior, but only realeased then. The game as we'll see employs the strangest elements of shmup design in its characters and gameplay, yet EXECUTEs them very well. Prior to the game's release, there was a prior version I'm assuming was the demo in the form of Hellsinker 0.95. That being said, I'm not too sure of this factor of development.

The main man behind Ruminant's Whisper and Hellsinker is a person named Tonnor, who's a great game designer as evident with this game — with his very esoteric yet elaborate game design elements. Unfortunately, he isn't active in the shmup genre specifically anymore, but he's still active on Twitter and is currently working on a puzzle game that's really confusing, of course.
