These ideas sound beyond stupid, but it's worth it.
Fishing: Make a tree or grass patch and there can be two checkboxes, Nonbreakable or breakable. If tree is breakable once you run into it a branch should fall down and pick it up , if grass patch breakable you press a key and a grass stem should be tied to the branch. When you make a pond or body of water there should be two checkboxes with fishable and nonfishable, If fishable black thingys pop up to fish you need to a branch with a grass tied to it and press a key to fish in it. When u get a bite fish a will move and go in random circles and you have to oppose it's direction for exsample if fish right you go left, vice versa,fish run away you pull in.

Swinging: Add a vine to a tree and once you jump on it you move left to right to get a stronger force, once you let go, YOURE FLYIN
