Kero Kero Keroppi no Daibouken 2 - Donuts Ike ha Oosawagi! (Japan)
An adorable Keroppi game geared towards little kids. Keroppi is a frog that's tasked with saving his friends. He spits music notes at enemies and can jump on them. At the end of each level, the boss challenges you to a kids game. Very cute and good game despite being a kids game.
