How someone who barely codes built this game in 4 days

Echo is a 2D side scrolling platformer where the hero is an AI vtuber streaming her run to a live chat that reacts as you play. The creator had almost no coding experience and made the first level in 4 days.

There is no game engine underneath. Claude Opus 5.5 wrote one from scratch, about 28,000 lines of TypeScript, and the world is drawn at runtime with synthesized sound.

Made by u/ZedTheEvilTaco. This write-up follows the original post; it is not an independent product test.
