This is a pretty nice game for your second upload to NG! The graphics with parallaxed semi-transparent clouds and the glowing effects give a nice level of polish to the graphics. I felt like the controls for the player's plane felt less responsive than I would like for a shmup and like some inertia was deliberately coded into it (or IIRC maybe Unity has built-in parameters for it when you set up input handling?). While everything is subjective, I feel like most players would rather have the controls feel nice and responsive, and have the challenge come from all the enemies shooting at them than handling the floatiness. I also noticed that often if I hold down space to spam shooting then it would shoot continuously for a while but eventually stop after several / dozens of seconds -- using Chrome on Windows -- although it's not a big issue to have to release and re-press space. I admit I haven't made it far into the game, it's pretty tough ^,^
