How to use the editor

Painting

Click / drag
Paint with the brush. Clicking a tile that already is the brush tile erases for that drag.
Right-drag
Fill a rectangle with the brush.
R
Rotate the brush.
E
Pick the tile, rotation and command under the cursor (empty space picks air, tile 1).
/
Edit the command of the tile under the cursor, e.g. g1 v3s2 d4. Enter applies, Esc cancels, empty clears. The Command box in the sidebar paints a command along with the tile.
Ctrl+Z / Ctrl+Y
Undo / redo.

Selecting and stamping

Shift+drag
Select a region.
Ctrl+C / Ctrl+X
Copy or cut the selection into a stamp; click to place it.
Ctrl+V
Stamp again. Esc stops stamping.
Del
Clear the selection.

Moving around

Space+drag / middle-drag
Pan. WASD or the arrow keys pan too.
Mouse wheel
Zoom.

Walls and view

G
The background wall column behind the cursor switches to its next style, and its top edge moves to the height of the cursor.
Shift+G
Clean view (hides the grid and overlays).

Play-testing

P
Play the level from its spawn. Press again (or Esc) to stop.
Q+M
Play-test starting on the tile under the cursor, with 45 invulnerability frames.
Q+R
Restart from the real spawn. R restarts while playing.
WASD / arrows
Move while playing.

Comments

C
Comment on the tile under the cursor (one thread per tile). Enter sends, Shift+Enter adds a new line, Esc closes.
Bubble
Click a bubble on the map to open its thread. Resolve a thread when it's done; replying reopens it.
Comments panel
Bottom left. Lists every thread; click one to jump to its tile.

Palette

Drag
Rearrange tiles (switches to "My order").
＋ Save
Keeps the current brush (tile + rotation + command), or the copied stamp, as a palette entry. Right-click a saved entry (●) to delete it.
Sort
My order, by ID or recently used. Order, saved entries and recents are only yours, not shared with the room.

Hue

Hue / Hue 2
Shared by the room. 0–199 wraps around; type 1e420 for gray. ↑/↓ nudge by 1 (Shift ×10).

Level size

Resize…
Add or remove rows and columns at any edge. "In the middle" uses the x / y numbers from the status bar: Insert puts new empty lines before that row/column (the old one moves up/right), Delete removes that many starting at it.

Rooms

Room chip
Click it to copy the invite link.
History
Backups are saved every 5 minutes, and before any import, resize or restore.

History

A backup is saved every 5 minutes (when the level changed), and before any import, resize or restore. Restoring replaces the level for everyone, and backs up the current one first.

Level size

Add or remove empty rows and columns. Tiles, commands and wall columns move with them, and a backup is saved first.
