Games built with it must fit in 3KB after compression, which works out to roughly 4000 characters, a size that fits in a URL shortened by X's 23-character link rule. Specs include 8 colors, a 160x144 CRT-style display, emoji-based pixel art, and BGM. Sample games include a Space Invaders-style shooter.","whyItMatters":"Kitao built the engine around X's link shortening, so the constraint is also the distribution method: a finished game can ship inside a post as a URL.","webCardHtml":"\u003cp\u003eThe cap is not arbitrary. Kitao set the limit to match X\u0026#39;s automatic shortening of URLs up to 4096 characters down to 23, so a game\u0026#39;s compressed code fits in a link. Games render at 160x144 pixels in 8 colors with a CRT-style option, and because the code budget leaves no room for image assets, Playload ships 8x8 pixel art tied to Unicode emoji such as the gem symbol. Sample programs include a Space Invaders-style shooter, a jump action game and a Lights Out-style puzzle. Kitao previously released the retro Python engine Pyxel in 2018.\u003c/p\u003e","blueskyPost":"Playload inverts the usual engine tradeoff: its 3KB ceiling, not its feature list, gets top billing. Takashi Kitao uses X's 23-char link rule so a whole game can hitch a ride in a URL.","twitterPost":"Takashi Kitao made Playload's 3KB ceiling the spec. X's 23-char link rule lets the whole game live in a URL.","threadsPost":"Playload reverses the usual engine pitch: the 3KB limit is the spec, not the compromise. Takashi Kitao leans on X's 23-char link rule so a compressed game can ride inside a URL. That turns the platform's link handling into part of the distribution design.","newsletterBlurb":"Takashi Kitao, known at Konami for work on the ZONE OF THE ENDERS series and Metal Gear Solid development tools, released the open-source engine Playload on October 21. Games must fit in 3KB compressed, a limit chosen to match X's URL shortening so a finished game can be posted as a link.
