Millie is a joyful and casual puzzle game that effectively engages cognitive skills such as problem-solving, spatial awareness, strategic thinking, critical thinking, memory, and adaptive challenge through its maze-like levels and diverse puzzles. It offers a moderate level of hand-eye coordination and fine motor skill development. The game's design encourages logical thought and learning transfer as players progress through its nearly one hundred levels.

Millie presents minimal risks. Its E10+ rating suggests very mild cartoon violence, but it lacks any significant dopamine manipulation, monetization pressure, or social risks due to its single-player, one-time purchase model with no in-game purchases or social features.
