Chase the Alphabets moving around!
Be careful not to get a wrong alphabet.

There are four stages; "Rainbow", "Deep Sea", "Galaxy", and "Chess Board".
At the stage of "Rainbow" and "Galaxy", chase alphabets in alphabetical order.
At the stage of "Deep Sea" and "Chess Board", you have to chase ones in random order.

Beware of "Walphabets". They appear in the "Galaxy", and "Chess Board".
If you catch a Walphabet by mistake, they turn the Alphabets upside down.
They enjoy annoying you.

If you get higher than 2500 points in all the stages, The level goes up.
The higher the level, the faster the alphabets moves about, and more Walphabets annoy you.

Just for your information, "Walphabet" means a bad alphabet.
"Wal" sounds like "悪" in Japanese, which means bad or evil.
I learned an English prefix "Mal-" also means "bad".
The similarity between "Wal" and "Mal" is somewhat interesting.
