You start in December with two weeks before the holiday crowds, then place lifts, trails, lodges and parking, make snow and open the mountain one day at a time, reading each evening's report for what to fix. A starter-resort button builds a first lift, trail and lodge for you, and there's a three-minute tutorial and a sandbox with unlimited money. It plays as a guest with no account. A four-player online mode, King of the Mountain, is separate.
How the creator made it
The creator says they built the first release in 11 days, with Claude Code writing the code while they designed and tested the game. They described each change, often with a screenshot, and had Claude build it on a branch, run automated scenarios and send back desktop and phone screenshots for review. When the resort issued too many refunds, Claude replayed a saved holiday day and traced the problem to guests losing their evening status on a shuttle. The creator says the first release included 63 automated scenarios running in Chromium.
