Development log

Notes from building Data Center Fan — design decisions, balance, visuals, audio and everything in between.

This devlog documents how the playable simulation is built: the economy behind facility growth, the capacity and SLA systems that create pressure, the isometric rendering work that gives each tier a distinct identity, and the performance decisions that keep the browser game responsive on desktop and mobile.

The posts use current in-game captures rather than concept art. Read them for concrete design notes, balance findings from automated runs, and implementation details from the live build. For operating instructions, use the game guide; for the full feature and progression overview, open the data center game brief.
