Yes, you can’t use custom images yet but you can try to use those in the ”Icons” section of the documentation and use the icon image that best describes your game’s mechanic/s.
If you can see clearly, the instructions use barriers and text, for the energy you can try to recreate it using an Item Spawner and hide a prop/barrier under the Item Spawner base.
That’s interesting. Do you have the map name? It could have been detailed pixel art, or maybe icon images on a vending machine, or item spawners, or barrier art, or something that we don’t even know about yet. This is all speculation btw, I have no idea of knowing what they did with no pictures.
I think gimkit should make a larger creative browser where you can see all the maps, not the latest map. B/c there are soooo many SnowBrawls or Battle Royale’s
