This is a deceptively hard game despite it's simple premise.
There are 100 levels which breaks down as 10 worlds each with it's own theme with 5 differences per level. Whether it's a size, colour, placement or other difference nothing feels overused or too obvious and just enough challenge to keep it engaging for days not hours.
The only slight gripe is that there is no kind of hint button and for maybe 3 levels I just randomly clicked madly until it finally found the last difference, but 3 out of 100 levels isn't bad and I could have googled it, but a hint button would have been nice just for a nudge in the right direction.
