NDS: Pirates of the Caribbean - Dead Man's Chest

I was testing the game Pirates of the Caribbean: Dead Man's Chest, and to my surprise I think the game is not too bad. However, I got stuck and first level and there's no way to save the game, and there is no walkthought on the web , so I am sort of giving it up for now. But the biggest problem is the contrast. The game is simply too dark to be comfortably playable on my on my Nintendo DS Classic. Maybe this game is my excuse to get a NDS Lite? Well, nope, not for this game.
