Not really a Guro artist, a Hentai Artist!
Fairy Fighting was more Hentai than Guro!
He makes hentai that has guro in it, hentai and guro are not mutually exclusive.
Just try and enjoy it. Failing that, make multiple save files by making copies of the game.cfg in the data folder so you can go back to the tamer sections of the game.
Eluku's been smart to slowly ease the inclusion of grotesque content the way he has, so that people, like yourself, don't get guro-jumpscared early on in the game, and that you can enjoy a massive amount of content up to a certain point before getting the ick.
Skipping the tiger part, as you said, probably isn't the solution, as it's more than likely an appetizer for what's to come, which has been confirmed to be Zombies.
Despite everything though, I implore you to stick around, you might eventually warm up to it, as I did during Fairy Fighting's development.
All we ask for is some respect
