So I played the demo last Sunday. To say the least, I was thoroughly impressed. The colors on the Samsung in the store were pretty vibrant and sharp. The game-play is great and easy to pick up. It took only two minutes for me to get comfortable with the game. I played through the first level and subsequently beat it. What you had to do in the level was pretty straightforward and linear, but I'm sure there are some puzzles in the games. In conclusion, I'm pretty glad I reserved the game a week before the actual demo playing. I can't wait for it.
