I like it
only improvements I would add is maybe a bonus unlockable character maybe smtin like a snake like thing that isn't bound to the ground? and sometimes the turtle flew off the screen so it would be nice to know where he is when he's offscreen like maybe make a marker or smtin to show where he is? and maybe not for the space ship but it would be nice if you showed where the next meteors were coming from (a radar on the side maybe?) other than that it's a cool game=)
