Not too shabby, but as it is, I'd call this more of a generative art showpiece instead of a game: fancy in function, but not necessarily fun or with long-lasting appeal.
Don't get me wrong, I had some good fun with it as the effects are nice and juicy and there are a decent amount of variations in enemy attacks to get through. But for a game that is procedural generated and has a big to-do about having so many galaxies of combinations, it feel like I was just playing the same game over and over. Yes, there were differences, but I felt like there were incredibly superficial changes, like how glowy my lasers are, or what new Rorschach ink blot test the enemies look like: at the end of the day, no matter what way the graphics changed, the attack patterns or enemy AI or what-have-you ever evolved to create a new experience like other games could do. And it doesn't help that it's a shooter game, which is already a dime-a-dozen in the 'my first game as an indie dev' box. I could see this being pretty neat, but I'd need to see some cooler and significant core gameplay changes come from the randomization that you can see other contemporaries do, particularly in the roguelike sphere.
Also that default glow is absolutely nuts, haha! Feels like a classic case where a dev wants to make their game flashy to juice it up, and overdoes it on the filters. Thank god there was the option to turn it down, but I tried to respect your vision and left it on high.
