Miracle Fly is an action game set in a Dream World where its characters are simply having fun; there is no story framing their adventures. Its central distinction is a deliberately unusual control scheme, which the game says may take time to get used to. Keyboard players can use W and S in place of mouse clicks, giving the basic act of navigating its stages a different feel from conventional action games.
The game offers more than 100 stages, with almost every one described as having a unique design. Cute bosses add a combat challenge, while New Game+ lets players use other characters after completing the game with an equal amount of play on each character. Those details give Miracle Fly a clear focus: varied stage layouts, boss encounters, and character-based replay rather than a story-driven campaign.
Its unusual input, stage-by-stage variety, and New Game+ character condition offer the more useful context for understanding what that activity represents.
