Okay so i tried your game.
Some feedback...
the intro needs some work, you only have simple lines of dialogue and then you go directly to the village without much context.
it was kinda funny how you don't even know the guild master but sends you to pick flowers and fucks you if you refuse.
there doesn't seem to be any reward for making said quest other than chosing the "fuck you" dialogue.
you are actually being "rewarded" for failling the QTE, that sure, i too love game over scenes or scenes were you lose, but i think that you also need to reward players for actually completing the content.
Also i think that QTE is kinda broken in how much you can spam it to instanly kill all enemies. not sure if that counts as "combat"
and there is only 1 quest currently?i think that for a demo you need a little more content. but i understand how hard is to make something all by yourself. specially if you don't have much experience you need to learn everything
i suggest looking at other games and took some ideas from there.
just my2cents. good luck.
