The visuals of the game are quite amazing and good, the mechanics are ok but the overall game difficulty is a bit over the top. You could basically start the game a be trapped in bullet hell from 2 big ships and 2 small ones. Overall the concept is quite good for an endless shoot'em up but the difficulty needs a bit of a rework.
Power-ups? Whats that? (in all seriousness tho, power-ups are too infrequent and far in between)
