Glad to know you had fun with our game!
The description's content is a part of the tutorial sequence we had planned for the start of the game. We encountered some issues and opted to put it in the description instead. We will develop the tutorial sequence in future updates so please stay tuned.
As for the spam click parry, the development team designed the parry system in the most satisfying way that it can get. We want to incentivize players in that way as opposed to punishing them hard for not playing as we intended. We are also open for suggestions as to how we can improve the game.
