need to add some things, its just shootatorials with diff graphics, maybe increase difficulty over time, add border, varying the enemy's path, more bosses something like that
wow, a lot of bug, i beat the last three or four level by pressing and holding one button, i like the idea, you just need to polish the game more 2/5 with the potential of a 3 or 4 if you fix the bugs (a lot have already been mentioned)
Like the music, good for first game , one bug i noticed was i didnt have to shoot some enemies, i would fly forward over them and they would die sometimes
