Hi. Sorry to hear that! :).
Some of the QTE's in the third day are supposed to be unwinnable. What happens after you lose the QTE? Does it just make you attempt it again?
If it makes you repeat it then it's one you are supposed to be able to beat. Earlier versions of the game had a bug where turning battle animation speed up meant that QTE speed also increased. So downloading V0.1451 from the main Itch.io game page should fix if this is what is happening.
If this isn't it then please give me some more info on what's happening and I'll look for another fix :).
Thanks!
