Oh wow, greetings from another text-heavy game developer! Although yours is definitely heavier, in more ways than one. I actually failed almost at the very start (guess I didn't hold SPACE for long enough), and then I failed again because I kept shaking one button, like it told me to do, until the next one appeared, and my clicked might've not registered well. And then I failed because I let go too early. Am I the one at fault? Or is it psychological warfare against the player? I'm starting to think that might be true. Just what do you want from me, game?!
~~It reminds me of the all toxic relationships I had in the past.~~
I lasted enough to at least pass the calculus bit, and then I believe I failed the QTE because I panicked and needed to look at the keyboard. And after that, because I used both of my hands to hold keys and ran out of fingers to click on yet another button. Arggh!
So, among the bugs I noticed, sometimes the '15+7-1' field doesn't clear, so when I click on it and type, I get 'answer21', which of course doesn't register and makes me fail. Sometimes the 'shake' and the 'hold space' options trigger a bad end even if I'm doing everything as told. Sometimes I'm not sure what the rules are: should I let go of 'space' to click on the next button? Should I avoid shaking it over other buttons? I'll investigate more.
At least the narrator believes in me and is proud of me.
