Sorry by advance, my english is not verry accurate, don't hesitate to ask me if something is not, or difficult to understand, I'll try to rephrase as best as I can
My appologies for your Nerve wracking, I can understand that reaction
Unfortunately, for the moment the QTE system is not really accurate, and we don't have a realy good feedback of what to do when you fail, and that make the experience a bit confusing.
If you want to try again, try to press the right key arround 0,5s after input appear.
The goal of the game was to create a stress situation created by the contraste of the chase, and the need to calm and slow down asked by the QTE system
Actually, when you'll press the right key, you will go up a bit, and when you fail, you will go back by the force of gravity.
We will correct and polish this system in future version, which I hope you will enjoy
