Pleasant, charming, and just challenging enough without being impossible. As others have said, the concept is common, but no other game like this has been as fun, nor have any others been as properly-paced. I never felt like the challenges were impossible or unreasonable, and I was very satisfied with how new elements were introduced gradually and with proper time to adjust. I am sure there were prettier ways to get all of the stars than some of the contraptions I laid out, but I was content that my own improvising got the job done each time. Very fun, very cute, and very well done. My only request is to have a more grandiose ending; that little guy worked hard to woo his princess and something romantic and sappy was totally in order.
