Thanks for the nod, really put a smile on my face!
One of the music tracks isn't playing back, just silence until the next level starts. I have to day I found some of your earlier music choices a bit more mood enhancing for the game, faster, intense. I may be misremembering.
I'm honestly ignoring the points system, there's no jeopardy because I keep forgetting to use the bombs. It's a thought that if you tied a bonus to clearing a level of all enemies of a particular colour or type, you might have more impetus to use the bombs, and sparingly. There is a lot about the aesthetic that I really like, but I just don't like the easter island head shape. Just dont like. Also seems too abstract a shape to offer an interesting target in a shmup. I'm not a fan of the tank either, tbh, although seeing it from above it works well.
How big are these 3d objects in terms of memory? There might be free library objects you can just drop in, but I'd love to have a go at coming up with something for your consideration, what format do you use for 3d objects? Just in terms of variety, I'd suggest avoiding having two item types use the same colour on the same level, and you can get more milage from the same models by turning vertically and/or horizontally, more exotic spacecraft designs don't have an obvious up or forward!
I don't want to patronise there, I wasn't sure if you planned on playing with this stuff, but changes in the rotation of like oriented objects, ie things coming in nose first but individual objects having differing roll rotations, would give a lot of variety for a (I guess) low cost.
Just a couple more aesthetic choice things. I find the dark laser trail a bit uncomfortable. It might be an artefact against a lighter colour, but lasers don't look like light emitters if they're not one of the brighter incandescent elements. That could be something cool to play with, but it just feels like a weird artefact atm.
Last thing. You get a sense that once an object has established a role - as furniture, set, a passive or moving target, you have to exclusively use it for that purpose unless it's part of a narrative. It just feels inconsistent and unsettling if these things are fluid.
I full on played forty plus levels last time. It's fun.

From playing newoshooter, it's really missing that stage boss that shoots back
