COVID Serpentis is a free browser-based pixel-art snake game. You play as a coronavirus on a world tour — infecting cells to grow, dodging vaccine syringes, outmaneuvering antibodies, and navigating quarantine walls. Every time you exit an edge of the play field, an airplane carries you to the next city: New York, Paris, London, San Francisco, Tokyo, Dubai, and Hong Kong, each rendered in hand-drawn pixel-art using pure HTML5 Canvas.
There are no downloads, no installs, and no sign-up required. The entire game is a single HTML file that loads instantly in any modern browser, on desktop or mobile.
