C got easier over time, but trying to get to Round 20 of A is fucking hard. The difficulty spike is real and I died trying to get any perfects and gave up

Fuck the difficulty spike in B. The accuracy doesn't actually go down as far as I know, but it certainly FEELS like it does. Birds leave the frame really quickly post Round 10 and getting a Perfect is insanely hard. I feel for anybody who had to use the Zapper for that.

I consider this 100% as I got all the Retro Achievements... with some liberal use of save states for Round 11+ of B when going for Perfect. A reminder that this was with a mouse, not a Zapper, and yet I still found it incredibly difficult.

I have to improvise due to a lack of zapper in my household. This is essentially cheating as it's a mouse, but oh well. I'm not planning on speedrunning, the NES itself is ~$73 I don't have, and the Zapper is ~$34 I also don't have.
It's really hard to perfect C, those discs go fucking fast.
Even harder to perfect 15C aaaaaaaaaaaaaa
