Shmups

I'm kind of curious if anyone has some "slower" PC shmups that they could recommend.

I used to enjoy playing shmups some years back, but kind of fell out of the habit, partly because a lot of shmups seem to have increasingly-focused on the "bullet hell" category, where a lot of the game focuses on keeping intense concentration on dodging through tiny spaces in a heavy barrage of projectiles, which I've never really enjoyed all that much.

Some things I'd be interested in:

• More space to maneuver, less of the screen covered by projectiles.

• Slower.

• I'd like to have more-complicated mechanics and planning than is typically the case for a shmup. I know that maybe sounds odd

I mean, a shmup is an action arcade game

but for example, I really enjoy Nova Drift, a roguelite Asteroids-genre game; there's a lot more going on than in the original Asteroids. Think, oh, maybe something more like Jets 'n Guns (which I've already played, along with its sequel).

• Horizontal or vertical scrolling is fine. I'd slightly prefer horizontal, given present-day monitor aspect ratios.

• It would be preferable to avoid low-resolution pixel art. I don't hate pixel art; I think that it's a good way to keep art costs down. And there's plenty of pretty pixel art out there. But because most pixel art games target devices with a wide range of resolutions, they tend to use a least-common-deminator low resolution. I'd like to take advantage of my monitor's resolution. A lot of indie games use pixel art, and a lot of shmups are indie. Just kind of feels like every shmup I look at is low-resolution pixel art, and I've gotten a little tired of the aesthetic, interested in mixing it up.

• Would like to support running at high Hz rates, stuff like 240 frames per second. I'm not worried about the game balance changing slightly at different frame rates or having comparable high scores to players on different hardware.

• Showing action covering the full screen. A lot of shmups only have action on part of the screen (in some cases, especially with vertically-scrolling shmups, because they were written for older 4:3 displays). I don't care about screen aspect ratio changes unbalancing the game slightly.

• It'd be nice to take advantage of the graphics hardware, do something more than blitting 2d sprites to the screen.

• I'd prefer to avoid chiptune (FM-synth or faux FM-synth) music.

• Having a steep learning curve, requiring a lot of reading, is fine. Most games that I really enjoy take many hours to "get" the mechanics, have a lot of levers to pull.

• Keyboard-and-mouse or gamepad is fine.

Anyone have something that they enjoy that they think might be something along these lines, want to give it a mention?

Thanks!
