Ame no hi wa Ooisogashi

Ame No Hi Wa Ōisogashi is an action game where you have to beat all mice that come out from the side of your apartment or from another building window before the floor is full of water. Because it has nails on the roof when the mouse jumps on them, they will fall and leak droplets of waters. You need to catch the drops of water falling from the ceiling with a cup. If it does not catch water, it will fall to the floor and gradually accumulate water. When the water on the floor reaches 2500 L, it is game over.
