Proto:Sonic the Hedgehog (Genesis)/Labyrinth Zone
This is a sub-page of Proto:Sonic the Hedgehog (Genesis).
 | To do: A lot of work on this page, document as many layout differences as possible, dump and add level maps. |
Labyrinth Zone is less complete than the previous three stages, lacking lots of things and not even being playable normally (skips from Sparkling Act 1 to Star Light). As a result, this stage can only be played via the level select.

The stage uses a completely different background at this point, and strangely changes Y position with each act (Act 3 has no background at all!).
- All three acts completely lack any water or object layouts, including signposts. This makes them impossible to complete; even exploration is difficult without debug mode.
- Rings, if placed via debug mode, use a glitched palette that makes them appear entirely black. The debug list also contains a Monitor and Crabmeat, a common sight for unfinished stages.
- Due to there being no objects, water current tunnels are non-functional in this build.
- Crystals have a different, smaller design. Interestingly, the 8-bit version uses these instead of the larger crystals seen in the final.

Brick wall tiles, which aren't seen in the final, cover certain areas of the stage. In the final game, these would mostly become areas with water bubbles that are opened with a button, which seems to suggest that these areas were meant to be air pockets before the bubble mechanic was introduced. It is worth noting that brick wall tiles do appear in the 8-bit version.

Pillar decorations are absent from this build too.
Act 1

The act seems to end prematurely in the prototype, with the camera scroll stopping at X coordinate 17BF, while in the final, it stops at 19BF. Not that it matters too much, since no signpost makes the act impossible to complete.

When the stage is first loaded, a graphical error can be seen when walking down the initial path. And as seen in the embedded video, the very start of the level contains a pretty weird vertical zipping bug that allows Sonic to stand on thin air and even outrun the camera for a few moments. This would later be fixed by adding a block object on top of the platform and disabling vertical looping in this act.
