CATALITY is a free sword-fighting platform brawler where cat knights duel, with fatalities. Each knight has their own blade, reach and specials: read your rival, parry, clash and launch them off hand-crafted battlefields. Ranked online with rollback netcode, parties of 2–4, plus versus CPU, training and a tutorial offline. Cute cats, sharp swords, very dark jokes.

Could you build this?
Partial A browser fighting game with characters, combat, and training modes is codeable with a 2D engine, but rollback netcode for ranked online play and polished hand-crafted content need specialised game-networking and art work.
What it would actually take: Use a web game engine (Phaser or a custom canvas/WebGL build) with a deterministic fixed-step simulation. Online play needs a rollback netcode library (GGPO-style) with a relay or matchmaking server and a ranking backend. The hard parts are deterministic simulation, rollback correctness and latency handling, and the art, animation, and balancing that make it feel finished.
