If you're using Mac and are unable to open the application ("The application "Lust's Cupid" can't be opened."), I may have a solution. Here is what I did to successfully open the app:
Right click the application and click "Show Package Contents." This should show you a single folder called "Contents." Open that folder, and you'll see 6 more folders. Open "MacOS," and there should be a single document called "LustsCupid." Now, open the terminal app. Type the following command "chmod +x " and then drag the "LustsCupid" document into the terminal window to quickly insert the path to that document into the terminal (or you could simply copy and paste the path to the document from your Finder window). Once the path to the document is in the command, you can press "return" to run the command. If it worked, the icon for the document should have changed to a dark gray box with "exec" written in green inside it. You may have to run the command "sudo chmod +x [path to the document]" instead of normal "chmod +x," but the first command worked for me.
I also have the glitchy, yellow and green filter when I opened the app, and I don't know how to even begin to fix that, but whatever, I'll see how big of a problem it is. This is the extent of my knowledge on how to fix the problems with the app, so if more show up, Idk what to do. But I got this far, at least
