Hey nicolasstag !
Have you tried running the app on admin ? Or downloading manually the game on the website ?
*Edit* It seems that it won't work in admin because the file is a bit heavy. If you really want to play the game you should download from the website :)
Sorry for the inconvenience !
I was just talking about the itch page : https://toxicpink.itch.io/toxicpink
Since you can't have access to the game from the app
