Sorry man, There isn´t any error logs when it crashed or froze or did the rewind bug/glitch.
And i don´t know how to these things. All you have from me is what i have said, sorry there´s nothing more man
This visual novel is bringing out emotions of people playing it.
Sadness,happiness and fear, all these emotions are let out while playing this and this is only a good thing for this game, because this means that people who are playing it cares about the characters in-game
And it seams like you are faster to put out updates on this project then i could ever imagined, but faster dosen´t always mean good, take your time on this project, many developers rush projects and they make countless mistakes along the way, such as: speling,artwork and story mistakes.
I do hope that you will take as much time as you need for this/future projects and the best of luck to you.
P.s Love your work
