Ok, I have got some much to say about your game.
First of all, as a fellow arcade shooter developer myself, I have to say that it is an interesting organic take on the space shooter genre.
The gameplay seems to be smooth, and the bright colours are definitely something to remember about your game. (Thanks for the epileptic warning)
Just a simple subsections of menus and BANG! you are straight into the action.
Good luck with your game.
