Your game is... Awesome! I think you can add a rpg base (weapons, power up..), and make shoot in other directions! Very good for a first game! "Tip jar : donate kreds" =D
I play this game 3 hours!
a PS3 game cost 50 $ and we finish him in 10 hour!
50 $ = 10 hours!
3 hours = 15 $
so you can sell your game for 15 $, or 10, if you are generous :D
