The constraints in this Zach-like are particularly challenging; timing and communication and math are handled in such an off-the-wall way.

I thought I was going to get clever by using a register as a value for the optional number of cycles parameter NOP or PLS but it won't let you do that! 😠 I guess it makes sense since the "preferred" way of selecting the number of cycles is with number of Os or Us (i.e. "NOOOP" to no-op for 3 cycles, "PUUULS" to no-op for 3 cycles when pulsing a signal), and you could obviously never set that arbitrarily with a register value.

It's a fun one but the challenge is real; I thought I was doing alright with my solutions so far, but the high scores are high (of course, Zach-like scoreboards always make me feel dumb).
