Got stuck on “green foxtail stick puzzle”, so I used the hint button, but first I had to watch a 30 seconds ad to get a hint... a hint that did not make sense, so i watched another 30 seconds of ad (again) thinking that the next hint would be better, but it gave me the exact useless hint.
However, there are no glitches, no interfering ad during the game, had save button and good enough game.
I played the cat in italy, and the palace... of this developer and I loved them both; this one however needs some improvement.
