For the level 59, try to put yourself bit above or below the spinner and just slowly click when you have bit of distance. I failed 100 times, but the with this I did it in only few attempts
3/5, I love this game, but it needs balancing and something more interesting than every weekday being same but longer. You could make every day different, so that there is only one characters which excels with their abilities on that day. The point system to buy new weapons is not needed.
Guide:
Play all chapters with Peter and use LaserGun as starting weapon. Buy LaserGun when you can and it should be easy enought to complete all the days. For the Experienced Farmers Badge, just play the first day with all the characters, preferrably using the their strong weapon to beat the boss and get two stars.
