This feels good to play - the controls, despite me being unsure about the mappings, feel responsive and good! I liked the visual style - the emissive materials on the big planet gave a good feel, you also had cell shaded style asteroids which was a cool effect too - not 100% if the glowing styles and that asteroid style blend together perfectly, but generally speaking it looked really nice! The on rails element is good - I just wish I knew exactly where I would be shooting! Obviously some variety in enemies, and the ability to destroy the "ENDING ENEMY" (spoiler) would have been great additions!
