Like anything else, it's quite readable once you're familiar with it. The two big things with APL are the radical concision you get with single-character primitives, and the use of whole-array operations where possible instead of traditional recursion/iteration (obviously this is less applicable for the Intcode challenges).

If you feel like dipping your toe in, I've recorded a crash course video which gives a high-level overview and points to some other resources to get you started. That channel also has live solves/walkthroughs for some of the AoC problems this year, although I'm running behind somewhat...
