Thank you for your opinion regarding the game, the game is meant to have the button spamming in order to win, to do this it uses the new Input System that does the same as the GetKeyDown() on the old system, as for the difficulty level, by default it’s set as easy and can be easily changed in the options menu, this decision was made in order to provide an easy to learn system so players can adapt to the more intense difficulties.
In regards to your comment in general, I’d appreciate if it were constructive instead of criticizing the author’s coding skills.
