incorporated other elements into the Dash function, such as scaling walls rather than just slamming into them. The Dowsing mechanic was created early on, based on the gameplay themes of discovery and exploration. Due to the introduction of Dowsing, the team did not have to create environmental landmarks for places and objects of importance as they had done in previous games. So players would not get lost in the terrain, they also introduced the marker beacons. Items were designed so they could be visible in any area, such as the bright blue Bombs. They were also designed based on their original location: those from Skyloft used a bird motif, while those from other Surface regions used more intricate designs. The Beetle acted as a replacement for the boomerang, as the team wanted an item that players could control. The Beetle and other pseudo-technical items gave rise to the ancient mechanical theme that appeared in the Lanayru Desert region. At Miyamoto's insistence, the more desirable items that were normally placed towards the end of a campaign were made available to players from an early stage. When designing items, the developers were faced with the usual problems of the interdependence of items and dungeons creating a chicken-and-egg scenario for the developers. The menu for Item access was also redesigned around the use of Wii MotionPlus. In past Zelda games, the team had made numerous new fields for player exploration, but this time they limited the number of overworlds to three and expanded their content so players would be able to fully appreciate them through repeated visits. The team also created the world based on their experiences with Twilight Princess: feeling that the overworld and dungeons were too large with puzzles too thinly dispersed, the team both sought to compact areas and have environmental puzzles in the overworld. The biggest difficulty was ensuring that players could reach areas quickly while still discovering new features and puzzles. The creation of the Skyloft overworld was due to difficulties connecting the three Surface-based overworlds due to drastically contrasting environments. The sky was initially going to be presented similar to the course selection screen from the Super Mario series, but this was changed to an overworld with its own quests and population so Link had a place where he could prepare for his adventures. An initial idea, when jumping down from the sky seemed unlikely to be
