is there any walkthrough for the current version?
There are several video play throughs - the best are by MoonSpawn and TGame on YouTube. There are not any current written walkthroughs because for the most part, the task list handholds players from day one through to the end of the current content.
it says to retrieve the ball and i just cant find the ball??
In the dialogue before that task became active - Becca tells you the ball landed in priscilla's back yard. Use the map to go to Priscilla's/Gerda's house. Click on Becca on the sidewalk. If you haven't got the rope yet to climb the tree in the backyard, you'll need to work on other quests until the rope appears in the smoking area behind the school.
I would recommend following one of the video play throughs I mentioned above if you get stuck. The tasks are timestamps in most cases - so you can use google or your favorite search engine to find videos time stamped by task: for example:
Taffy Tales Search for the ball with Becca google search results in this -
