You are a developer with a bad computer. Take quick projects for money, upgrade the machine, then start searching for jobs and take the opportunities that come up. Money per pulse and pulse speed are the two numbers, and the shop and the lottery are where it goes.
There is a showcase for finished projects, an achievement list and a wiki the author wrote. The lottery costs a cent and mostly takes it. It is a small, dry joke about the job sustained for longer than you would expect, and there is about an hour in it.
