Excessive adds placement that make this game unlikable. No autosave feature, n with EVERY saving action follows the adds, plus when I let the screen idle, to think about the puzzle, here come the annoying adds😞it's a pity, the super annoying adds covering the descent part of the whole game.
For some reason, I could only find 8 digit buttons for the keypad (you need 9). Exasperating! So I retried only to failed again. Only on the 3rd attempt, did I manage to find all 9 of it. Game wasn't too difficult but finding all buttons was tricky.
Too much blind clicking
Worst navigation. Very sluggish
Very hard to navigate and see. Even on a 7 inch screen.
