Its pretty hard to get enough bits for anything except movement speed and shot speed unless you have the zero write and are on the level with the big squares. Wait for 2 or 3 of the big squares to appear on the screen at the same time and use the zero write. You get around 200 bits. Then die so you can do the process again until you have as many upgrades as you like.
Very nice game with fluid and well-polished graphics and animation. There are endless postitives I could give to this game apart from the graphics and containing a sunglasses wearing shark that creates thousands of explosions. Although all the positives, there are cons. The gameplay gets boring after a while of playing due to the long levels and repetition of aeroplanes. Still a 5/5 from me :P
And everone that is saying that there should be a looping background.. It's "The end of Space" so there won't be space if space has ended.
@ChaosJon You could atleast make it look like it is the end of space by putting an abstract animation in the end of space. And why the shoddy rocket? You couldn't even be bothered to delete the background of the rocket?
And the healthbar doesn't work. You might aswell remove it. Oh yeah... the bullets for the enemies somehow come out of their faces? Put an offset like you did with the player so it spawns from outside the MC. 1/5 for FAIL GAMEPLAY.
