File differences from tutorial?

I downloaded the "2D Rougelike" game to get a feel for Unity (Just downloaded it), but when I watched the first video I noticed a major seeming file difference; I had no "Assets" folder, but instead a "Completed Game" folder. I figured that wouldn't be too bad, if at all, (finished games have to have assets right?) but as he moved on to adding the PlayerIdle and PlayerChop animations to the Player, this actually stopped me from moving forward. Since I didn't have the Assets folder, I didn't have the right sprite sheet! When I opened it up, it was the right images, but I couldn't select any of them! Did I do something wrong, or is this just an old version that's been changed, and if so, is there a new video link?,I just downloaded Unity, and tried going through one of the Tutorials, the 2D Rougelike game. As soon as it started I noticed the menu looked different, but I attributed it to setting differences. I have open the proper file that got downloaded (and the right video), but these differences didn't really matter until the second video, where he uploads both the PlayerIdle and PlayerChop animations. Since I don't have the same "Assets" folder he does, I tried looking through the files it did give me, and found the sprite sheet, although it opens differently and I can't select any frames. I figured I could, instead of dragging and adding as a new animation (since I have it already in the completed game folder and it automatically grabs them from there) I just set the Animation in the "Animation" property to "PlayerIdle", but I can't select a second one. Now I probably had it wrong from the beginning with the difference in folders, but I downloaded the only folder offered for the game. Am I supposed to have different files (The Finished Game instead of the Assets folder), or is the linked video too old? (2015 Feb)
