I played a few rounds and enjoyed the game, scored 335,600
I think it performed above expectations in Graphics, Smooth movement & Animations. The boost and the shields are great additions.
The one thing that bothered me were the planets, while they somewhat revolve they look like a flat 2d sticker, maybe you can find a way to give them a more natural 3d feel, maybe have it as a rotating 2d animation that gives off the effect of a revolving plant. Another topic, in space you continue to move until you counter balance to advancement. In the game you decelerate over time to a halt, maybe it by design, im not sure, but just flagging.
Lastly, if you can add an option for continued fire that would be great.
