Thank you for your support and feedback. If you have time to play it again, you should try to get the true ending and other secrets. The aunt is waiting for you. For the mash QTE, I bought it from the 3rd party in Unity asset. I asked the developer of this QTE system. Unfortunately, he also can't answer how to fix this problem. As the warning in the description, it depends on the keyboard especially some kind of mechanical keyboard. I'm very sorry for your inconvenience. I'll fix other buggy things and improve my game. Thanks!
