Help! I have a problem with GMS 2. I don't have a project file, but i have a executable .zip file. And it is not project folder in GameMakerStudio2 folder. Is it any choice to return my project?
I don't think so, but you could also try asking here GameMaker Subreddit.
Did you lose your project file? you should make it a habit to make backups, otherwise you would need to start over.
