Creator guide · Base assets

Make something for your base.

Draw a floor, wall, tileset or piece of furniture. Preview it at game scale, keep a copy, then send your art for manual review.

Submitting starts a review. It does not automatically put your art into the game.

01 / Start here

Choose what you’re making

Open Base assets, choose an Asset type, then select Start new asset. Your previous asset goes into Saved assets. One game tile is 16 × 16 pixels.

16 × 16, 32 × 16 or 32 × 32 px

Floor / ground

Choose a 1 × 1, 2 × 1 or 2 × 2 tile pattern in the classic editor. The complete pattern repeats in both directions so you can check the edges for visible seams.

16 × 32 px

Wall

A wall face that repeats from left to right. Keep neighboring edges consistent.

64 × 64 px

Tileset

A 4 × 4 atlas of sixteen 16 × 16 cells. This is artwork, not an autotile rules file.

Choose your footprint

Item / furniture

Set floor space and height separately: a rug lies flat; a cabinet rises above its footprint.

Sizing a floor pattern

In classic floor mode, choose Pattern size, then Start new asset or Apply size. Draw a horizontal motif across 2 × 1 tiles, or alternate colors across all four cells of a 2 × 2 checkerboard. In your base repeats the whole drawing without rearranging its cells.

Resizing keeps pixels at the bottom center and adds transparent space when growing. Shrinking asks before cropping the top or sides; cancel to keep your work, or use undo after applying. Save a project copy before resizing if you want a permanent backup.

Sizing an item

Width in tiles and Depth in tiles each accept 1–8. Height above ground adds 0, 16, 32, 48 or 64 pixels above that floor space.

PNG width = width × 16
PNG height = depth × 16 + height above ground

For example, a 2 × 1 tile cabinet with 48 px height above ground has a 32 × 64 px drawing area. A flat 2 × 2 rug has a 32 × 32 px drawing area.

Use Apply size to resize the current item. Pixels stay anchored at the bottom center; shrinking can crop the top and sides. Use undo to restore cropped pixels.

02 / Make it yours

Draw, import and preview

Use Pencil (B), Eraser (E), Fill (G) and Picker (I). Zoom in to place pixels; check In your base to see how the art reads beside the character.

Keep empty space transparent. Erase pixels around furniture instead of painting a background behind it.
Import artwork PNG accepts a PNG that exactly matches the current drawing dimensions. Choose the size first; the editor does not resize your import. An import can be undone.
Preview floor shows real game floor textures. The optional Furniture reference ghost helps compare scale. Floor references, ghosts, guides and the character never enter your exported artwork.
For a tileset, use Preview tileset cell to check each of the sixteen cells as a repeated floor. The preview does not assign automatic edge or corner rules.

Tell us what an item should do

Choose an Item behavior under What should it do? and describe the interaction in Behavior notes (optional, up to 2,000 characters).

For a slot-machine cabinet, choose Game / arcade and write: “When a player interacts with this cabinet, open the existing casino slot game.” Name the intended game if you know it.

Use plain language. These are design notes for the owner, who manually handles behavior, placement and collision if the art is accepted. Submissions do not run creator code.

03 / Before you send

Keep an editable backup

Download project: Your editable pixels, size, asset details, behavior notes and reference settings in a project file. Use Load project to restore a separate copy.
Download PNGs: Your clean artwork as a native-size PNG, plus asset metadata JSON. Use these to inspect or share the art; keep the project file for editing.
Saved assets: A shelf of up to 20 assets, autosaved in this browser’s local storage. Use Open saved asset to return to one. Download a project before deleting it.

Browser storage is not a portable backup. Clearing browser data, using a different browser or changing devices can leave your saved shelf behind. Keep downloaded project files somewhere safe.

04 / Share your work

Submit for review

Submit your original art, or art you have permission to submit. Check that you can share any material you include. The editor’s reference images are there to help with scale and color.

Treat submission details as public

The review issue includes your artwork, artwork name, artist credit, contact information and notes, including behavior notes. Only include details you are comfortable making public. Use a public handle for contact; leave out private email addresses, personal details and secrets.

Check the native-size PNG, transparency, repeated edges and item footprint. Make sure the artwork is not blank.
Enter an Artwork name and Artist name for credit. Both are required and must be 2–60 characters.
Add an optional public contact handle (up to 120 characters) and optional reviewer notes (up to 2,000 characters). Explain the intended use and anything the reviewer should check.
Select Download project, then Submit art. Wait for the result beside the submission controls and keep the review link if one is provided.

Ordinary submissions are separate from contests. Use Submit art outside a contest. Contest entry has its own availability and rules; a closed contest does not make an ordinary submission a contest entry.

Entering the base-art contest

When the base-art contest is open, floors, walls, tilesets and items can enter from Base assets. Character cosmetics are outside this contest. Enter your Discord handle, read the contest rules, accept the contest terms and use the contest submission button.

Each person may enter up to 3 entries; a tileset counts as one. Every eligible entry is judged out of 100 points: 40 pixel-art quality, 30 game fit, 20 technical readiness and 10 community. Larger artwork does not automatically earn more points. Contest art must be entirely your own original work, with no AI-generated art.

Keep your project backup and the returned review link. The team checks eligibility and judges entries; a successful submission is not an acceptance or a prize award.

What happens next?

The owner reviews the art, credit and notes, checks dimensions, transparency, visual fit and intended behavior, then decides whether and how to integrate it. Watch the returned review for updates or questions. Acceptance is not guaranteed, and there is no promised review or release date.

Keep creating

If something goes wrong

A field or PNG is rejected: Read the message by the submission controls. Check required names, character limits and exact image dimensions, then correct the project. Your drawing remains in the editor.
The connection fails or the server is unavailable: Download the project and PNGs to keep a copy. Your project remains editable; submitting is not needed to save or export it.
You are unsure whether it arrived: A failed response can happen after the artwork was received. Check any returned review link or existing review before trying again. Avoid repeated submissions while the outcome is uncertain; retries can create duplicate reviews.
You reopen the editor: Look under Saved assets in the same browser, or use Load project with your downloaded file. If the shelf is full, download the projects you want to keep before deleting an older asset.
