Pepoo Arena

I wanted a party game that starts in one click: no install, no account, on computer and phone alike, ready to play with friends right away.

Four modes: free-for-all against three AIs, 2 vs 2, training, and online in a private room where you invite up to 3 friends by code or link.

Six arenas (from the classic island to a volcano and a giant turtle) and eleven items so that every round goes off the rails, with keyboard and mouse or touch.

The engine strictly separates simulation from rendering: the simulation draws nothing, which makes it testable without a browser and ready to run on a server.

Rendering uses Canvas 2D, and multiplayer goes over WebSocket, with rooms and snapshots of the game state.

The game is live, free and with no sign-up, on computer and phone.

Separating simulation from rendering on day one costs almost nothing and changes everything later: you can add arenas and items and check them without opening the game.
