i have played this level many times. I get enough orange pieces are to get a second monkey, but no where in the level do I see a box where more monkeys can appear. In my game I see 3 different areas. Never progresses beyond that.
This is my start screen. Doesn’t have 40 moves and doesn’t look like the start screen in the video. this is the third section. As you can see no orange box for monkeys to enter.
