There's too much searching for them. This was the reason why I never finished the game; the collisi were just hidden away at the most annoying places. The reward for finding one was great, I'll admit it, but the amount of searching kills much of the entertainment.
It's certainly not a game for everyone so I'll suggest you try it out a bit more. If it's still not your deal, get a refund or switch it with another game.
