Well, apart from the fact that the whole apple deal was Newton, not Einstein, and the rather horrible spelling mistakes in the texts, it is an OK game for a brainteaser. Downsides being the sometimes rather odd physics engine and.. wtf.. pay for more levels?... -2 for that one.
I found this game interestin put ok.
I like this game and graphics style.
A decent game
A pretty decent physics game but V dies equal mg^2. 7/10
-2 for the fact that I have to pay for "extra levels".
So 5/10 overall.
