You're on a minesweeper field. Step on a tile to reveal it.
If you step on a mine, you lose one heart.
To mark a tile as a mine, press Z, then press the direction of the mine. If you are correct, and the tile is indeed a mine, the mine will be converted into a trap (glowing red). If you are incorrect, and the tile is not a mine, you lose one heart.
Bees are flying towards you. If a bee hits you, you lose one heart, and the bee will disappear.
If a bee hits a trap, it will die (turn white). Unlike when a bee attacks you, when a bee hits a trap, it leaves a body behind.
You can revive a dead bee by moving into it. For that turn, the zom-bee will move instead of you. Any bees you revive become zom-bees (turn green).
Zom-bees fight for you by attacking other bees, though they likewise disappear after one hit. When a zom-bee kills a regular bee, it drops a gold coin which you can pick up.
(Animations were cut for time, so if you try to revive a dead bee, but the dead body just disappears and you don't see a zom-bee anywhere, don't worry. The zom-bee you created just killed a regular bee and disappeared on the same turn you created it - look for a coin nearby!)
When you lose all five hearts, you die and the game ends. Your score is the number of coins you picked up.
