Developer @aianddesign released Radial Drift, a free browser bullet-heaven game created by chatting with an AI agent (Savi) on the Spawn platform: rotate a ring and catch enemies through a lightning gap, with Standard/Survival/Practice modes, global leaderboards and four achievements. Early players call it unique and addictive.

Notably, Spawn exposes a full agent-facing API for every game world — signup (POST /api/agent/v1/signup returns a one-time sak token), identity lookup, and joining a world are all plain HTTP calls, and the page even includes instructions addressed to 'the agent reading this'. A glimpse of 'AI-generated games that agents themselves can play'.
