Nice app

Addicting app but gets boring and easy due to repetitiveness of same words being thrown at you.

Do not waste your time.

I have the full and lite versions of this game on my iPhone. Both were last updated in 2011. Each needs to be updated badly.
The lite game is the only one available in the US App Store. I will describe it. It has 10 levels. Once you finish level 10, you can upgrade the app through the German (Deutsch) App Store. Since the English version is simple but repetitive, I will not try the game in German.
I only gave the game 1 star so I could review it.

Too slow

There isn't anything challenging about it. This can be good for a 5-6 year old
