Sunny forest find numbers

A hidden-object game narrowed to one target type: the digits zero to nine are concealed in an illustrated forest scene, and finding all ten completes the level. Restricting the search to numbers makes it friendlier than the usual cluttered-attic variety — you know exactly what shape you are hunting, so the difficulty is in how well the artist hid them rather than in reading a list. Made for children and perfectly playable by anyone.
