Look after a tiny console pet

Combine input, memory, decisions, and a loop into a whole program.

cpurecipe

Let's give the pieces a shared purpose. Pip wants three berries. Type feed to offer one, look to check progress, or quit to leave. This is a tiny game: it has an action, changing state, feedback, and an ending. Replace start.yh in your console project with the complete program below. There are no images or downloads inside the game. It uses the same text console we have already met.

Notes and source

Play once to the ending. Play again and quit early. Then change the goal to five berries everywhere it appears.
