カード (KAADO)

This is a little experiment made in 4 days.

You are given a japanese character and have to choose between 4 options for the pronunciation of the character, if you get it right your コンボ (combo) increases and every 10 right guesses you get rewarded with a confeti explosion. Can you reach a コンボ (combo) higher than 500?

You can choose if you want to be shown hiragana, katakana of both types of characters. (Sorry, no kanji support, at least for now).
