This might be unpopular, but my suggestion would be to increase the price of the items and possibly lower the price of purchasing the knuffel.
I've had the most fun with this event when I had to get the currency for the items, but I feel I don't have the same excitement once I have them all and have to throw only for the knuffel. And if I'm not mistaken we can get the entire set by lvl 6 (330 points).
The greedy side of me wants the downtime to be reduced too, but I find waiting for the entire minute to go by more annoying when I miss. If it is possible and not hard to code, my suggestion would be making the odds a little harder, but getting rid of the downtime for hitting again when we miss and only keeping it when we land a hit. Not sure if it's possible, but I'd enjoy clicking to my hearts content until I hit and then have downtime to enjoy the hit (hope this makes sense

)
