It has come to my attention that the NSIS installer script I’ve been using for ALL of my installers will delete the entire installation directory when doing an uninstall. For anyone who chose the default option, which is to create a new subdirectory in the “Zachtronics Industries” folder in “Program Files”, this is not a problem; the game-specific subdirectory is the only thing that will be deleted. However, if you’ve installed the game directly into a directory with other files, DO NOT USE THE UNINSTALLER, as it will delete those files too.
I’ve uploaded new installers that lack an uninstall option for now, and will hopefully figure out a better solution in the next few days. If anyone else encountered this problem in the past (but didn’t threaten to rip out my entrails) I apologize to you too.
