This is the DX version of Irresponsible Vending Machine, and it has a lot more "Special" and "Others" items, with no more ads.
You can find words on the button of the vending machine, and if you push the button, the item comes out with sound.
The words are written in English, Japanese hiragana, katakana, and romaji. You can ascertain how the Japanese words sound with alphabet by romaji.
Use this app to make your child learn how to read words, and if interested, learn Japanese, too.
