Hi — There has been a lot of study behind the psychological aspects of games and why/how we play/interact with them. So whilst I agree with you, I would like to point out that I made the game to be challenging for myself. People of the right metal will complete the game regardless of the difficulty (that is another area of psychology).
Whilst in the progress of writing the game, someone from the Scirra forum spent two hours completing the game. My point is, there are people out there who enjoy a challenge and these are the types of people that the game is targeted at.
Thanks for the feedback though...
