Thanks for the feedback! Controls were initially ment to be not left and right, but full circle, that should feel a lit better, but I had quite a lot of issues with the system and no time to implement it properly. As for power ups, they do work, although shield can be blown up by asteroids right away, once it applied. Also the idea was to make you think whether you want a steady safe extra life type of power up or rush through the level with x2 speed. As for debree gathering it had few more power ups on earlier stages of development, including launching more ships at the same time and increasing range, but i had to scrap it, because it resaulted in spending way too much time on choosing the power up thus lack of concentration on asteroids themselves.
