Visible differences from the final version of the game include:

• The zoom in and out buttons use arrows instead of magnifying glasses with plus and minus symbols.
• The energy crystal icons in the meter for energy crystals collected are blue instead of green. The counters in the bottom right corner for energy crystals and ore stored are also smaller.
• The O₂ symbol on the air supply meter glows and is positioned slightly more to the right. It is also incorrectly written as O².
• The message panel has some slight difference
• Several notification tabs are displayed that are unused or changed in the final version of the game, including:
  • A blue energy crystal.
  • A lit stick of dynamite, likely using either "DynamiteTip.bmp" or "info-dynamite.bmp".
  • A blue energy crystal next to a "no power" symbol, similar to the unused "Crystal_nopower.bmp".
  • A white LEGO brick, likely using either "info-construct.bmp" or "BuildingTIP.bmp".
  • A Rock Raider peaking through a hole that was likely intended for when a new cavern is discovered, using "cavefound.bmp".
  • A power path, using "info_path.bmp".
  • Three stars presumably meant for when a Rock Raider has been trained, using "info_Training.bmp".
• The numbers displaying how many of a certain type of notification there are are on the opposite sides of the tabs, and some are above the maximum limit of nine that exists in the final game.
• An information button is present in the top row of buttons, possibly intended for the planned in-game encyclopedia.
• The menu back button uses a different, more simple arrow design.
