Didnt know it was possible to miss scenes in the story. I reached a point, where something in Pisca's room was sparkling. When I interacted with it, she just scolded me what I was doing there. And any conversation with her ended in "First hurry up and finish your mission" - awkwardly, the mission seemingly never ended according to Pisca's opinion, and then I was in the sky. lol.
I am not sure if I ever will continue/finish the game, since it stretched itself too much already. But still thanks for the instructions.
