Thanks for playing! The information gap seems to be the sticking point for a lot of players. I didn't want to rob players of discovery, but it's true that the move list is a bit too vague. There's probably some magic combination of textual info and opportunity to experiment that would satisfy people lmao.
3S style parry was implemented at one point, but in a PVE game, it trivializes encounters. The enemies in the demo reward aggression by having large gaps in their attack patterns to exploit. Allowing you to take your turn at any point means you can ignore their patterns by reacting quickly.
