Fixed a misspelling of "despawned" as "despanwed" at the end of the Steam section.

The game's internal data structure defined a level as a single 32×32 layer of static tiles, plus one optional actor per cell. It was thus impossible to create otherwise intuitive combinations like a key on top of [[gravel]], because both the key and the gravel would have had to occupy the same space. | The game's internal data structure defined a level as a single 32×32 layer of static tiles, plus one optional actor per cell.

The [[DAT]] format invented for MSCC inadvertently exposes this arrangement to level designers, allowing a level to have ''any'' two tiles stacked atop one another. The game wasn't designed to handle two actors or two static tiles in the same cell, so various unusual effects may occur.

For Chip's Challenge 1 tiles, the most notable improvements are the ability to place an item on top of any kind of terrain and the ability to place thin walls, in any combination, atop anything else at all. The other new layer is dedicated to new CC2 tile: the no sign. Canopies are the same tile internally as thin walls, so, as a consequence, they can be placed on any cell, optionally in combination with thin walls. | |||
Weirdly, the C2M format allows for multiple tiles of the same layer to be placed on the same cell, which results in all but the last tile of that layer to be [[Despawning and Respawning Glitch|despawned]]. | |||

[[MS]] also has the [[clone block]], used to indicate the direction of a block cloner. This is a tile in the sense that it can be placed within a level, but it exists as an editing trick and is not intended as a distinct game element. In all other [[ruleset]]s, dirt blocks have a direction like every other moving object, so a separate clone block is unnecessary. | [[MS]] also has the [[clone block]], used to indicate the direction of a block cloner.

These tiles are possible to place in a level due to being a part of the [[DAT]] format, and only exist as placeable tiles due to quirks of the implementation. Most of these tiles with graphics behave the same way a [[wall]] does, with Swimming Chip behaving closer to an extra player in a level. | These tiles are possible to place in a level due to being a part of the [[DAT]] format, and only exist as placeable tiles due to quirks of the implementation.
