Lots of polish juice and content in this one.
I enjoyed the tutorial bit, although it overstayed its welcome a tiny bit, but it was fun.
I would appreciate the ability to pause.
I can see the design appeal of the bullets that hurt you, but I didn't actually find them fun. With the hectic gameplay it doesn't seem worth it to actually pay attention to the next bullet. I got further and had more fun once I just started ignoring them and just tanking the damage, putting 100% of my attention into aiming and dodging.
