[Flash Single-Player] [~2014] Vertical Scrolling Bullet Hell esque game where the player is a fighter plane against other planes

Platform: Flash Web Game, potentially on Kizi.com?

Genre: Bullet hell / Sci-Fi / Vertical scroller

Estimated year of release: I know for certain that I played it in 2014, it probably released a few years before that though

Graphics / art style: 2D, i remember vividly back then drawing scenes from the game where the bullets to dodge were yellow circles with reddish/orange outlines, flashing I'm pretty sure, and they had gradient transparent edges. The enemies and scenery gave the vibe of an alien earth, i remember clouds and sorts of industrial city type scenes in the background, and large alien looking air ships

Notable characters: Not a very character based game as far as I can remember, it was more focused on the planes and gameplay

Notable gameplay mechanics: It was a vertical scroller, the player was at the bottom of the screen and I'm pretty sure you could move in all four directions, probably with WASD or arrows, but it might have been just left and right. The enemies would come from the top edge of the screen facing the bottom of the screen, and they would shoot the yellow circle bullets in unique directions based upon which type of enemy it was, some went straight, some shot in bursts of 3 that fanned out.

Other details: I can draw up an imitation scene and put it on Imgur if it's necessary, just tell me in the comments, but I hope it it should be findable with simply my details
