What IsoCity is
IsoCity is a city builder game by Andrew Milich. An isometric city builder with 59 placeable building types, R/C/I zoning, power, water, rail and subway, pedestrians and traffic — plus a co-op mode. Built with Cursor and open-sourced under MIT; the title screen says “Made with Cursor” itself. It is a 9.2 MB download that loaded in 1.7s when we tested it.
IsoCity: measured
We loaded IsoCity in a real Chrome and played it by hand, and recorded what it did. Blank cells are facts we could not measure, not zeros.
| Download | 9.2 MB | Total bytes fetched on first load. |
|---|---|---|
| Loads in | 1.7s | Time to the load event on a desktop connection. |
| Frame cost | 6.2 ms — comfortably inside the 60 fps budget | Cost of one frame while playing, sampled in a visible browser we drove by hand with vsync off — so this is how long the game takes to draw, not the rate your screen refreshes. A 60 Hz display allows 16.7 ms; 95th percentile 10 ms. headed Chrome (chrome-devtools MCP), 1280x800, one tab open, 300-frame rAF probe taken after Load Example; AMD Radeon 610M |
| Renderer | 2D canvas / DOM | What the game draws with. |
| Requests | 21 | Files fetched — a low count means a self-contained build. |
| On a phone | Fits a 390px screen | Measured in a 390×844 viewport. |
