This is a GameBoy Advance game where you play a series of “microgames” one after the other. Each one lasts a handful of seconds, and you have to figure out what you have to do, and what the controls are before you run out of time. The aim in each section is to finish a certain amount of them without losing all your lives. Each level is themed around a different character, and has it’s own intro and ending cutscene.
I bought this when it originally released and loved it, playing it again today it absolutely holds up. It’s funny, fast paced, with great art and the minigames are brilliantly designed. Following the retro achievements meant that I unlocked a series of side games and distractions that I didn’t know existed. I didn’t get all of them though, as it became tedious to get a high score in each individual one.
