Under rating threshold (hideshow)
Not the run-of-the-mill game for this site as the developer is an educator. I can't help buy wonder if this is, perhaps, not the ideal place for "testing" this as you must be a minimum of 13 y.o. to be on this site. Nonetheless, 5/5 for having a method for teaching children. During the test at the end, it asked to find the "hot air balloon" and I failed to find the photo of my mother-in-law. ;-)
