Here is an improved version of my Ludum Dare entry "Perception". The game is not perfect but it's much better than the original version. All comments are welcome.

To quickly present the new gameplay, concentration and perception bars are now uncorrelated and must be maximals to find your keys in the grass. Naughty pigeons will perturbate your concentration, click on them and they will fly away. Look around to find them but be careful, don't turn too much or your perception will be altered and you won't see birds anymore !

How fast will you be to find your keys ? My highscore is 1 minute and 2 seconds !
