電車タイマー

The target age is from about 2 years old.
You can use it when you like a train, like "wait another 3 minutes!"
(My child likes electric trains and made for when waiting for rice)

If you tap several times during the waiting time, a big train will come.
(I made it a balance that makes me interested, not playing too much like a game)

I would be pleased if it would be support for parenting.
