I thought this was a really cool game and a great addition to the series. What really sold it was how there were so many things going on. The designs were all nice and it was another one of those games that you could really experiment with. The sounds/music were also very nice and it really motivated you to keep up with the game. I should have realized sooner to use the Shift key. You get to that with the level that has the upside down words.
What was also cool was how fluidly you (the player) moved through this. It might not have been that well detailed, but it's still great to see it all in action. This series will just never stop having new and exciting things in it. It makes you realize how good these puzzle games are for your brain. Now I feel dumb for not beating it.
