OpenNono is an open-source JavaScript port of Nono o Sagase! Level 41! ~Nono to Fushigi na Ehon~ (乃々を探せ！レベル41！～ののと不思議な絵本～), the 2019 April Fools' Day Minesweeper maze minigame from THE iDOLM@STER Cinderella Girls: Starlight Stage. It is also my first serious attempt at frontend web programming.

This port is hosted here. Both mouse and keyboard controls are available. Consult the help page for more details.

• Current mine density is fixed at 15%, make it configurable
• Current Tomodachi Block density is fixed at 1%, make it configurable
• Display the active idol's position while flagging
• What happens when an Open skill reveals a flagged tile?
• Profile and optimize the code (might not be worth the effort)

• 🦀🦀🦀🦀🦀 Almost all references to the iDOLM@STER series are gone!!! 🦀🦀🦀🦀🦀
• It is now possible to use 5 Open skills of the same kind, even for shapes which were owned by fewer than 5 idols from the original minigame.
• All Tomodachi Blocks now reveal 3 random mines (i.e. stage 2 / 3 variants are not implemented).

Everything works out-of-the-box on any modern browser that supports ES6. There is a Grunt task that concatenates and uglifies all JavaScript files.

• Initial release
