This is such a good game. A total classic point-and-click game with excellent music, graphics (for it's time) and voice acting. The store line is so complex, amazing, and not at all what you would expect. The puzzles are challenging, and yes, there is some "back-and-forth" that is required, (i.e. you will have to go from one side of the game to the other to get an object in order to move on). The back-and-forth though, while mildly annoying is totally worth it, in the context of the puzzles over-all, and the plot which continually makes you question, "what is going on here?"
One of the best made games of the era in my opinion. Play it if you're a lover of classic point-and-click, or if you've never played a classic, PNC, you should take a break from the "moderns" every once in a while, and see what modern games have been built upon :)
