Editing How to platformer

The rooms in the level are 9 blocks wide and 5 blocks high, and all of them—except for room 1, rooms 1005-1100, rooms 1652-1656, rooms 1658-1676, and rooms 1678-1815—feature a checkpoint. From rooms 1-1650 and 1820-2024, the layout follows a repeating pattern: the player progresses 9 rooms to the right, moves up to the room above, then travels 9 rooms to the left, ascends again, and continues this sequence. Sets of rooms, usually 100, are grouped by a specific theme, such as platformer game-modes, seasons, or other concepts. Each set has its own music, so the background soundtrack changes whenever the player enters a new set of rooms. These sets usually increase in difficulty gradually, starting with very easy rooms and progressing to more challenging ones toward the end, before the player advances to the next set of rooms. Every room, except for room 1, rooms 1652-1815, and room 2024, has its own name displayed in the top-left corner, which may describe its contents, reference another level, or convey a message to the player. Additionally, every room except 1651-1815 has its number displayed in the top-left or top-right corner. The colour of the rooms typically changes every 10 rooms, and most rooms feature simple patterns or basic elements in the background.
