Thanks for your feedback! I'll take it into account :D
I just played your game. It is super awesome. I had the privilege of playing arcade shoot-em-ups in arcades when I was a kid and your graphics (including the shaders that you used) capture that look.
Have you considered just enabling auto-shooting? I was just holding A the whole time.
Besides that, I think the concept and execution are on point. Oh... but I'd like some sort of marker that tells me I've won. Maybe... a glitched screen that says "synchronization succesful", or something like it.
