To move, tap the corresponding buttons (i.e. —> to go right)(arrow keys also work). Closely watch what the demo finch does to learn what to do (if you’re confused after watching him, re-click the green flag). Tap “tap” buttons. For the water hose, drag it to water the flour. If you are stuck with an item in your hands with no way to deposit it, tap “Discard all items”. Grab fresh pizzas and put them in the box (if mobile, put the pizza on your arrow to move). Put the boxes into the truck. It takes a while to cook, so you can go to the upgrade section on the right to check things out. The truck leaves after a while.
