A Grimoire Interactive studio

A cozy vector studio for game art.

Jello, the Marmaloom familiar — a friendly marmalade blob in a purple witch hat with a gold star charm
Why it feels different

Built for the couch, not the cubicle.

Most vector tools are desktop apps squeezed onto a screen. Marmaloom starts from the tablet and the pen, and only shows the controls a game artist actually reaches for.

A pen that behaves

Palm rejection, finger-to-pan, pressure. Draw open paths, drop nodes, and pull curves like the pen tool you already know.

Non-scaling strokes

Outlines that stay crisp at any size — the way game sprites need them. Booleans you can preview before you commit.

Your palette, front and center

Color-first inspector, a swatch grid you can reorder, Lospec palettes a tap away. No hunting through dialogs.


One canvas, three ways to draw

Vector today. Paint and pixels next.

Switch modes without leaving your artwork — the theme lives in the frame, never on your canvas.

Vector

Shapes, paths, booleans

The mode that's live today. Precise, resolution-free, game-ready.

Paint

Brushes with texture

For the soft, hand-drawn passes vectors can't fake.

Pixel

Grid-snapped sprite work

Down to the pixel, for classic sprite sheets.

Where the name comes from

Draw it here. Watch it weave into your game.

When you're ready for the game-dev layer, Marmaloom threads your art onto your laptop, packs your sprites into atlases, and turns drawings into animations — no export dance.

1

Draw on the tablet

Sketch a sprite on the couch, save it. That's the whole ritual.

2

It lands on your laptop

A tiny helper writes real files — per-shape, per-group, or one sheet — the moment you save.

3

Your game picks it up

Point it at your project folder once. New art just appears where your engine expects it.

Sync

Straight to your laptop

Save on the tablet; real files land in your project folder seconds later.

Atlas

Packed for your engine

Bundle sprites into a texture atlas with trim and nine-slice, ready to load.

Animate

Bring it to life

Turn a stack of drawings into frames and preview the loop before you ship it.


Jello the familiar
Meet the familiar

This is Jello.

Part marmalade, part good luck. Jello turns up in the quiet moments — an empty gallery, a long save, a spell gone sideways — with a tip instead of a spinner. Personality lives here, so your canvas doesn't have to carry it.

Empty gallery

“No spells yet. Tap ✦ New and we'll start weaving.”

Saving

“Threading your shapes together…”

Something broke

“That didn't take. Nothing's lost — let's try once more.”

First launch

“Welcome to the loom. Pick a canvas and draw.”

Come weave something.
