But mostly that
If you're having trouble getting through the game, try my cheats. Only the Windows version is supported, but I'm hoping you're playing on a PC. Here's the GitHub link: https://github.com/Swish-XD/Love-Maniac-Cheats
Regarding the issues with the cheat: open the game's root folder and type "cmd" into the address bar. Then, type the name of the game's .exe file (if the name contains spaces, enclose it in quotation marks—e.g., "Love Maniac.exe"). Launch the game, trigger the error, copy the logs, and post them either in the GitHub Issues section or directly here as a reply; I'll see what I can do.
Do you think you could also make a cheat menu thing for ADULTTALE by ADULTTALE?
It's got a pretty similar premise.
