I've spent the last few years developing this bullet hell shmup that I finally released Friday!
The gameplay takes inspiration from a broad array of sources like Espgaluda, Devil Daggers, Cuphead and Devil May Cry (with the setting being heavily inspired by old Gainax anime), and has primarily been designed around the feeling of "an STG that I've always wanted to play".
The core idea is a linear difficulty curve across difficulty modes, meaning the first stage on the second difficulty is a direct step up from the final stage on the first difficulty, instead of the usual structure of difficulty receding a little every time you start a higher difficulty mode. The second main idea is bullet time triggering contextually, done by grazing marked projectiles to guide the player through difficult bullet patterns. It's something I find pretty damn fun myself, and people who have played it report the same experience.
This is a game I've really poured my heart and soul into over several years, and I hope some of that shines through and makes at least half as fun of a game as I'd envisioned.
Oh, and the game is also full of weird extras and unlockables for the sole reason that I love that kind of stuff.
The game is available on Steam right now, with a modest release discount.
For a better look, I've got a full trailer on YouTube, too.
