Slap City was originally envisioned as a mini-game in Ittle Dew 2 before being reworked into a full title. The scrapped mini-game had intentionally poor presentation, being locked to 30FPS with interlacing, something that was not retained in Slap City given it's focus on competitive play, and a low-poly style inspired by the original Super Smash Bros. The polygonal alternate form of Fluffy Fields, where the Clone Team is fought in arcade mode, is based on this version of the game.
