Theme + Categories

'Secret Spaces' refers to the quiet places you can escape to. Whether it's a peaceful, sunlit glade or a cove that acts as a respite from the horrors of the night, the space is yours. 

When creating a scene in the style of Sylvain 'Tohad' Sarrailh, you'd want to aim at having something that feels alive. To achieve this, three elements are important: colour, light, and depth. To match his style, you should emphasize the variety of shades and search for a wide colour range. Pay attention to shadows and light, as lighting is a fundamental part of Tohad's work. Combining these elements will help you to produce good image depth and lively scenery. Exemplary work coming soon.

Since this is a game jam, we also encourage you to add narrative, interactivity, and gameplay to the 3D environment you create.

The specific categories that you will be judged on are:

Homes and HideawaysMystical Woods
Abandoned Cities
Where do you go to recharge? All variants are welcome, as long as it feels like home to you :)What wonders abound deep in the forest? If you look closely, you can almost make out something glowing in the grove ahead...How can there be so much beauty after the fall? So many mysteries lie waiting to be uncovered - I wonder who will be the first to uncover them.

More inspirational images (and full-size variants of the above) here as well.

About Core

Core is a new (free!) game creation platform that lets you build, publish, and play games. 

Core makes prototyping and iteration fast, so it’s a great platform for game jams, especially if you want to quickly set up a 3D multiplayer experience. You can get started making games right away using thousands of free, high quality music, sound, and art assets, with no coding required. 

Core is backed by the power of the Unreal engine, and it lets you create and customize your game as you see fit, from custom game logic in Lua to primitives and models that you can kitbash together with visual effects to create an elegant scene


Here's how to quickly make a fully functional game in Core, in only 10 minutes! (yes, really)

And here are the results of our last environment art contest, to inspire you and show you what's possible with the upper limits of the engine!

And here's a quick video for our fantasy tileset that shows off building in Core:


  1. Core Documentation - Packed with tutorials, examples, and references, this is the place for all you need to know to use Core.
  2. Core Academy - Check out the ‘Intro To Game Design’ course for an even more guided experience to make your idea into reality.


How are entries judged?
- Popular vote is used solely as a preliminary ranking. The official judges, Tohad and Core employees, will rank the final submissions based upon the categories listed above. The judges decisions are final, as they have the sole discretion in determining the winners.

How do I submit my entry?
- Create any game (can be an empty one essentially), and use it when you submit. The actual submission we'll judge is the required custom field when you submit it to the jam - a URL link to your Core game. You also must choose the category to submit to. Screenshots/videos/gifs in the game (on Core or itch) are a small but nice bonus :)

Can I submit multiple entries?
- Sure! You can only win one prize, but every entry you provide increases your chances of doing so.

Is Core kitbashing or making new assets?
- Both! New assets are created within Core by combining a wide selection of complex and simple shapes, hindered only by your own imagination. Our art director's blog post describes the ideology behind it all, for those who are curious.

Are the detailed legal rules anywhere?
