1. Space inside a movable box

- Preserve recognisable landmarks across unexpected spatial connections.

- [Patrick's Parabox](https://store.steampowered.com/app/1260520/)

## How it works

The player learns how places are connected to each other. Antichamber explicitly builds exploration around a non-Euclidean world, rearranging spaces and corridors that connect to each other in unusual ways. Description Antichamber.

## Variants

### Variants and applications

<a id="family-07-variants"></a>

- Non-Euclidean connections. Spaces connect in ways that cannot be predicted from conventional geometry. <a id="variant-metroidbrainia-07-01"></a>
- Dependence of transition on direction. Entering from the other side or moving in the opposite direction leads to a different result <a id="variant-metroidbrainia-07-02"></a>
- Dependence of transition on route history. The sequence of previously visited places matters <a id="variant-metroidbrainia-07-03"></a>
- Looped space. Going abroad brings you back to another part of the world; this property can be used to avoid obstacles <a id="variant-metroidbrainia-07-04"></a>
- Nested spaces. The object contains an area that repeats, reduces, or transforms the external space <a id="variant-metroidbrainia-07-05"></a>
- Connection between layers of the world. A change in one dimension, scale, or view affects the corresponding location in another <a id="variant-metroidbrainia-07-06"></a>
- Hidden addressing principle. A teleport or transport network is controlled by coordinates, symbols, or a calculated address <a id="variant-metroidbrainia-07-07"></a>

## Context and limits

In metroidbrainia, progression depends heavily on the player's knowledge: an open rule changes the available actions, routes, or decisions. 91 mechanics in 12 groups, progression techniques, training techniques and edge cases are stored here. For a project, check what knowledge is acquired, how it is derived, what it reveals, and where it is reused. Specific game solutions are not disclosed.
