Nice game, but only 4/5. Why, you ask? Because of the missed opportunities. Especially the end was just boring. Just as DeathShrimp described, I had the feeling something is absolutely wrong, especially regarding the mother. I expected a revelation or something, but all I've got was "Thanks for playing" and the useless message of the items. I was disappointed.
I love it for the same reason I love Canabalt: It's simple and it's fun. A game doesn't need complex mechanics to be fun...we all played hide and seek as kids, and it's not very complex, is it? By the way, my highscore is 525276, second try. I'll get a better one soon. :) (I kick ass at Canabalt) And Canabalt is even mentioned in on of the Achievements...nice.
