I'm making a game that takes heavy inspiration from Zelda games like Ocarina of Time, Wind Waker, and Twlight princess, i.e. OoT-lineage Zelda as opposed to BotW & TotK and games that stem from Link to the Past. It's not a fan game, of course, but if you like OoT/MM/WW/TP/SS, then you'll (hopefully) like my game.
One central aspect to nail is the camera system these games use. There's some variation, so I've picked one to "clone." I'm basing this camera off of Wind Waker's. It has a default mode where Link runs around the camera with left and right and pushes/pulls the camera with up and down. If you wait long enough, the camera will move to be behind him, and of course there's a Z-targeting mode that will force the camera to move behind him and let him strafe. Finally, there's a free camera mode that works like the camera in a lot of modern third person games.
In terms of movement, there's walking and running, but jumping is relegated to hopping across short gaps in these games, and I've implemented that system as well.
