Get food, get wood, buy a cursor, buy an upgrade for the cursor. It is a civilisation clicker cut back to the studs, with tier 1 matter converting into tier 2 and a prestige counter sitting at zero under a work in progress label.
The author calls it a basic game because it is easier than most, which is a fair description. There are perhaps fifteen minutes in it before you have seen every button. Worth a look if you want to see the skeleton every larger clicker is built on, with none of the presentation on top.
