@zatnosk Your concept looks neat indeed!
I had Sekiro in mind tbh, but those fights require many options to be fun (jump, roll, guard…) and 1 button feels too limiting. Your idea is more elegant though. Reminds me of barebones vs games like FOOTSIES or DiveKick.
My main concern is that while minimalism works for those because fighting humans make it interesting, IA could get boring without enough variety.
Thanks for the input, I'll be sure to tell you if something comes of it!
