Level Editor

The Level Editor is a feature where players can choose to test things out on their own or invite a friend to join in. Once you've completed your masterpiece you can upload it to the Level Lobby. This is where all uploaded playlists can be downloaded, played, and rated by others.

In the Steam version, levels are uploaded to the Steam Workshop. As of June 2021, levels can no longer be uploaded on the Xbox version due to issues and the potential shutdown of the server running them.

Controls[]

Use the "A" button, or Enter button on keyboard, to place a block.
Use the "B" button, or Backspace on keyboard, to erase a block.
The Right Trigger/Tab key allows you to select a wide selection of blocks to place. It can also be used to duplicate the block that the cursor is currently sitting on, although some blocks do have limits on if they can be duplicated this way or not.
The Left Trigger/Shift key allows you to change attributes of the level, including the background, sky color, both block colors, block designs, game mode, level time (except in Arena modes where it's forced to 2 minutes), and the color of cardboard plants and water.

Hex Editing (Modding)[]

On both versions, you can hex edit your levels to get blocks, sky colors, and game modes normally not found in the Level Editor, so you can make better and unique levels. However, it is possible to corrupt your levels. Luckily, it is really uncommon to do so, and only happens if you try renaming a level improperly on the Xbox version or adding or removing data resulting in a file size change without changing the level size values to account for that (You should not add or remove data at all on Steam playlists).

There are level attributes that cannot be changed in the Editor itself, and this is the only way to change them:

- Level Size

- Special Background

- Foreground

On Steam, playlists are stored in one giant file containing the hex data for all levels. On Xbox, the level data is separated into individual extension-less files inside an Xbox Package file. This is important to note if you plan on porting levels across versions, as you have to paste the data in the correct place, and you should make the level you want to replace the same size as what you're replacing it with to avoid damaging the playlist.

Follow this guide on how to hex edit your levels on the Steam version, and watch this video on how to do it on Xbox 360 (you can not do this on an Xbox One or Series X|S system, you need an Xbox 360 for it).

Try Arena modes against AI characters instantly to test it out.

Limits[]

Some blocks have limits as to how many of them can exist in a level. Some blocks have combined limits, where any combination of them has the same limit. Any block not shown in the list below has no limit. These limits cannot be broken even with hex editing, with one exception.

Spawn Cage/Hidden Spawn* - only 1 can be placed in the Editor, but a level can have up to 4 of any combination in it.
Gem*/Strawberry/Gem Runner/Strawberry Runner - 7 of any combination
Yarn*/Pumpkin Pie - 1 of either block, you can't have both in the same level.
Exit [0*, 1*, 2* and 3 Gems]/Secret Level Entrance/Hidden Exit* - 4 of any combination (Weirdly, an infinite number of Secret Level Entrances can be placed in the Editor itself, but they count towards the Exit limit when testing or when the level is saved. This can cause them to remove actual Exits from existence if they are placed underneath them.
Golden Hat Spawn* - 16 (Weirdly there isn't usually more than 5 in any given campaign level, where these are usually found.)
Cloud - 128
Spike Block - 64
Fan Block - 32
Wings/Jetpack/Whirlybird - 16 of any combination
Rocket Pad/Button-Powered Rocket Pad - 32 of any combination
