I just downloaded the game and when the I start a new game, it crashes. I don't know why, I play few similar games that I downloaded here in itch.io so I don't know why this one is crashing.
If there is no crash message in Renpy style, then it's on your side.
One of only things that come to mind is possibly pc thinking it's a suspicious file, it can happen rarely and randomly with some games in Renpy that use a custom launch icon.
- You could try -> deleting the game and trying to reinstall/reunzip
- Try installing in a different folder (Desktop)
- Pause any Antivirus that might block it and see if it can launch
It happens very very rare and there is no simple universal solution if that's the case.
