Colossal width to this game, shit is insane, and a good depth in the gameplay department where this could serve as an actual pokemon alternative, the visuals are amazing and the animations + audio really sell this. Im giving it…
BurekBeats2026-03-22★★★★★
It's a major step-up from the developer's previous game (Free Fuck Ticket) and there are countless references to it. Once more, you play as an ugly degenerate who somehow gets an overpowered ability to essentially fuck any h-girl you encounter…

Came to goon.. Stayed for the story.. Why was this game actually as good as it was? xD Had me thoroughly hooked by the end. Amazing work, will definitely check to see if they've created other projects. Thank you
