You think it is an adventure but I think it is a trap more than anything else. The idea of going to this mysterious summer forest all alone was not good and look you have already lost your way in the forest. You will have to go exploring the entire forest, solve a number of puzzles do what is needed to be done to activate the portal because that is how you will be able to complete your so called adventure. There are helpful things and creatures in the forest but they will only help if you fulfill their demands. I am sure that you are wise enough to figure out the rest of the things all by yourself.
