Alright, it's pretty fun arcade shooting game!
This is a secret but I was actually confused your game with someone else game because the name and the genre are being similar, I already rate your game so don't tell anyone else about it.
I don't have anything to add as I'm not experts on arcade shooting, I haven't even beat something like Gradius so I can't say much.
The game use the theme well, visual end everything else seems alright so that's it.
That's all I guess, if I missed something or saying something wrong, let me know.
