You see two Pokémon and pick the one you think has the higher value. The game uses real data from an API, in this case the PokéAPI. That makes it a good small project to understand how APIs work in a real scenario.

For that kind of tool it works fine. The problem started when I turned the idea into a game. In a higher or lower game you do not just fetch once. You fetch multiple times per round.
