"Almost, but not quite" sums up this episode well.
I tried the demo. Meh.
But a month later, I kept hearing how great the second episode was. Once I saw the entire first series up on STEAM for buttons, I made the purchase.
I'm glad I did.
While I wholeheartedly agree with Gamespot's reviewer when he said that the humor didn't translate well, and that the endless clicking got old, he was right.
But after sticking through the game (and it didn't last that long to begin with), I was happy with the Strong Bad quirks that were offered: the ability to play an 8-bit game in a game, the ability to create your own episode of "Teen Girl Squad," the collections, etc.
If you're a fan of the web-series, try the demo of the second episode. Telltale definitely learned their lessons after creating this first iteration. If you enjoy #2, get this one as well.
