Play Sylvester and Tweety (Proto) Online
You control Sylvester stumbling through chaotic Looney Tunes levels—missing jumps, dodging anvils, and getting outsmarted by that smug little bird at every turn. The janky prototype physics just make his failures more hilarious.

Game Overview
Man, Sylvester and Tweety (Proto) is such a weird little SNES time capsule. You play as Sylvester, of course—clumsy, determined, and constantly outsmarted by that tiny yellow menace. The controls feel a bit stiff at first (it is a prototype), but there’s something hilarious about watching Sylvester faceplant into a wall after missing a jump at Tweety.
The levels are packed with Looney Tunes chaos—Hector the bulldog shows up to wreck your day, anvils drop out of nowhere, and half the platforms seem designed to make you fail in the most cartoonish way possible. Graphics are bright and chunky, like someone froze a Saturday morning cartoon mid-frame.
It’s janky, unfinished, and honestly kind of unfair sometimes… but that’s also what makes it fun. You can tell the developers were just throwing ideas at the wall to see what stuck. If you’ve got nostalgia for 90s platformers or just want to see Sylvester suffer in new and creative ways, this proto’s worth a spin.
