Nice idea, but...

...It's way betetr to only give the front name instead the whole name.
Lots more people would like it that way.
Change it if you want.

errr..

not bad, BUT I only know their first name, like stalin, or diana.
and I was so frustated about how to write charlie capline. we must write charlie cHapline.

Good but!

The game is actually quiet good, not to hard if you know your history.
But the problem is that it is alittle to selectiv, I typed in Einstein and got that wrong on him. I can accept that one, so I typed albert Einstein and got that wrong to. You just need to fix this little bug and the game would be wastly improved.

Not bad, but much room for improvement

As I said, the game is ok. But here are some points that could be changed:

a) Allow at least some spelling errors (e.g. Josef Stalin / Joseph Stalin) to avoid frustration.
b) Remove the way too easy ones like e.g. Britney Spears and Brad Pitt
c) Add the hints only after a certain time, e.g. I knew "Steven Spielberg" just from the hint, not from the picture.
d) The Highscore list doesn't make much sense, if always the same people appear.
