It seems like a gimmick, but if you are a Japanese learner, mastering the hiragana (and katakana) are absolutely crucial to establishing foundational Japanese. And fortunately, Hiragana Pixel Party does a good job at helping you commit these to deep memory while having fun. Think of Parappa the Rappa around language learning - it is that type of rhythmic gameplay. Recommended if you are at the beginner to intermediate level of Japanese learning.
