5,000 point gem
In the first non-tutorial level, while you are still flashing, jump up and to your left. There is a hole in the wall which you should jump down. Once you fall to the bottom, run to the right, collect the gem, and go up the ladder and to the left–but be careful to not drop from the tunnel and right on top of the Pawkeet. – krawkfan101
Invincible starts
When you first start the level and Hannah is “blinking,” she is invincible. This is a good time to try and get treasure in hard to reach places. – Cow_Goddess_12
