Visually this looks great, the style is off the charts - though I do have to dock one point for your two primary colours being red and green! It's the most common type of colourblindness - 8/100 men have it, so choosing different colours is one of the best things you can do for accessibility :)
Gameplay-wise, it's pretty good - rail shooters are a lot of fun, but I think this one probably needs a little bit of balancing. Other people have said the same so I won't hammer the point too hard, but I did also end up just spam clicking to get rid of the red missiles.
Dynamic soundtrack puts you on 5/5 for audio, great job there - I played on web so it wasn't really synced, but it is very difficult to do that on web so you get a pass there lol. Good job :)
