You won't have to do this in the future.
As described in progress report 0909:
I adjusted the plausibility of this fight.
Catgirl's attack prompts will be more obvious and players will have more reaction time.
It's just that I have a lot to deal with at the moment, so I can't give an exact time for the update :S
===============================
And, I’ll save this winning approach.
The player did not commit any illegal behavior. (For example, modify HP, modify invincibility time...etc.
Players use the rules of the game to avoid the cat BOSS's action test. (Restraint attacks will not kill players & Cat BOSS has no attack actions other than restraint attacks.
Allowing players to win can be seen as a reward for leveraging this knowledge.
