You face a boss at the end of each one of the levels, mostly Sonic villians and other original characters (the kidnapped werewolf Sonic also poses as villain). You must guide your character through the scenarios like a platformer, but engage in fight scenes with horny Sonic characters and monsters along the way. Gameplay features a lot of pixelized sexual action and kinda hardcore fetishes. Your objective is to face everyone on your way and destroy the pink slimy monster that was formed from the love potion. The story as the name suggests is about a love potion that accidentally got spread through the air by twin sheep sisters and affected almost all the characters and led them to get always horny and want to have sex with anyone. Zu is another female one, but it must be unlocked. You can also choose to play with Zeta the Echidna, an original character, a cartoon portrayal of the main developer.
Here you can't play as Sonic, instead you get a bunch of secondary characters (almost all female, except Tails) from the Sonic the Hedgehog universe: Miles 'Tails' Prower, Amy Rose, Rouge the Bat, Blaze the Cat and Cream the Rabbit.
2008 indie erotic Sonic platform fighting game by The Zeta Team, unrelated to Sega and the Sonic Team.
