Hello! First of all I love this game! I remember downloading it a while ago and playing till Episode 9! I absolutely love the concepts, art, and story (and it's the right kind of work to scratch my Inclusive Magical Girl Video Game itch). Again, love this piece of work, I can feel all the effort (and time, and revisions) you put into this! Now, onto my second point...
OMG HELP- I downloaded the new update just now and I got a bazillion error codes- I tried playing without them (but I had to play the game from the start), and I got to the end of Episode 2 then it crashed... Is it something wrong with my computer? Or the itch.io file? Cause it seems to work fine for everyone else- 
Hi another user had a similar error. I copied my response from them here
Basically it's trying to pull a file that no longer exists for some reason (it wants to use the old main menu background art despite it being replaced) i've seen similar bugs before where it's for some reason trying to grab files or displaying images sometimes that haven't been used in an extremely long time.
deleting the game (and any other stray copies you might have) and reinstalling it entirely seems to work. it's not an issue with entirely fresh installs, though, and it's not an error i can replicate on my end either
If deleting the cache and reinstalling it isn't working you might wanna try grabbing it through steam instead since i feel like it's an issue with the way the itch app is installing updates.
