Mind mapping tool that uses space to hold information

I recently saw a landing page of some mind mapping / knowledge base tool. The tool has 'quirky' way to hold information on the space - they used maps that looked like a game-map and claimed something 'we do know that information is not flat'. Unfortunately I forgot what was the tool name but I really want to try it so if you can help me find it I'd be grateful. From what I recall the landing page was blue and they had similar graphics to this promoting their tool: https://img.craftpix.net/2017/11/level-map-2d-game-backgrounds-1-720x480.jpg

Of course if you know something that sounds similar I would also like to see it. Thank you.
