Hey, sorry but no, it doesn't have skip gameplay button, it's for a reason though. I don't want to make just visual novels, I want to make engaging gameplay in both current game and my next one. So even if I'm okay with cheating by modifying the save of the game, I won't be making anything to make player skip gameplay entirely.
There is a ''skip day' button that you can't overuse or bad ending appears (if you are close to overusing you just need to play one day fully to reset it) and you can't skip bosses, so that's the minimal of gameplay I really do want to keep.
