There aren't any available for free; the $5 tier on my Patreon gives access to a cheat menu. However, I've done my best to avoid most situations where you'd want to skip stuff; the only actual grindy bit should be getting Ken early on, which is optional. Note that Act II and Act III each add a new way to generate Ken faster. I have plans to improve that system, but they're currently on the back burner.
Once Ruin Me is "done," I'll probably make most of the patron-only stuff available to anyone who "owns" the game (whatever that looks like). Cheats won't ever be a fully supported feature, as I don't consider it a big priority to make sure they work without causing bugs elsewhere.
If anyone is tech-savvy enough to mod/hack the game on their own, feel free! It would be relatively straightforward, and the basic variable names are very guessable ("ken", "depravity", "permissivity", etc.).
