The trailer showcases new presentations of existing mechanics, such as playing the ocarina. The remake features significant redesigns of the original adventure. IGN's demo reviewer also noted redesigned challenges in familiar rooms, new dialogue when speaking with old acquaintances, and updated controls and more refined art that changed the feel of combat and puzzles during the demo.
Visually, the demo description highlights lighting in the forests, moss and mushrooms on tree bark, and details in Link's attire. The demo footage reportedly runs at 60 frames per second, with the forest-themed music performed in a new style. These impressions are based on limited demo content.
