Try to run your last save from the very beginning, if it doesn't work, start a new game in an empty save cell, go through the plot a little and check for masks, although you still have to take the test in a ninja costume again on android because due to an error or bug, the level that you passed by the time with the mushroom forest is not saved, but you will be lucky if In the last playthrough, you bought a gray mask with a smile that will allow you to move between levels, if not, then good luck going through it all over again.
