I've played the last couple of events, Didn't like the last one but tolerated it due to the available prizes being quite strong.
This one I won't be continuing after my initial 1 attempt for several reasons.
Do not like this mechanic at all. Feels like a kids game. Looks like a kids game and I wouldn't download a game of this type.
Prizes of fragments; There hasn't been a clear explanation of the continuation or direction these will take and I have no use for previous event golden fragments, any forum queries about it have been ignored so I'm assuming no one knows and I have no idea if I'm storing them for nothing. I don't see the point of collecting them/completing quests/spending time doing the mini game for nothing and wasting several weeks doing so. Not to forget their placement has reduced prizes down on the grand prize row.
It takes too long to play, you're also restricted to playing on a timed basis if you want to use all the tokens.
Oh and a jumpin pumpkin with an etched out face sounds more related to a Halloween event than a fall event and I can't think of any logical reason why we're collecting coffee cups for either a baking or fall event.
One positive though, due to the quest tab reshuffle, it's made it easier to ignore the event as I don't need to see the quest flashing daily for the log in currency reward.
