What the hundred games are built with, what we reach for next, and where to look if you want to see how.

THE PROJECT

• Build LedgerEvery project, measured from its own git history. Days, commits, lines, what is live.
• RelayThe house template for daily link-first games. Two files of game, everything else built in.
• Silly Ninjas artEvery sheet in the Silly Ninjas kit: the five ninjas with their poses and emotes, and ten worlds of props, ground and cast. Shared by Silly Ninja Defense and Silly Ninja Squares.
• The padOne script tag and a PlayStation controller plays a game that was written for a mouse. It sends arrow keys, falls back to WASD, then to walking the buttons on screen, then to a drawn cursor that clicks — whichever the game turns out to want.

THE PEOPLE

• Dan ViauBuilt tally, the analytics in every game, and the Zen redesign of Hex Smash that became the house look. Also the arcade hub and Hex Smash Ninja.
• Gustavo KonradRebuilt Lore Wars and BREACH on Solid, and built Wizard Battle and Overland.
