There was a similar game on the GBA before, but its name is different from this game. It's called WarioWare. The game introduced this time has different content from WarioWare, but it's equally interesting. It will give you a lot of mini-games under very tight time constraints, and you need to complete them in an extremely short period of time. The time is so tight that you may not even have time to figure out what the game is about. Don't be afraid of failure, try more times, I'm sure you will love this game.
