Was pretty hyped to try this game out, until it didn't work, starts up to the menu like normal and when I tried to start a new game, just shuts down. I tried running as administrator as previously stated in the changelog, but it's whatever the main menu was great enough for me.
Hmm... that's an interesting issue, I (Rriik) have never run across it, but if it persists even after deleting and redownloading all the files it likely means it's related to the persistent data (saves, config files and the persistent dialogue history used for skipping). If you can open the game and look at the options menu, there should be a button to "Browse user data" which will open up the persistent directory. Try deleting the persistent.json file and restart the game, and let me know if it fixes the issue. (The folder location should be under "C:\Users\<user>\AppData\Roaming\Godot\app_userdata\Identity Visual Novel" in case you can't open it through the game).
