Ragdoll Mayhem Maker – a physics-based level editor for my indie game

https://ragdollmayhemmaker.com/

Hi all, I’m the developer of Ragdoll Mayhem Maker. This started as an internal level editor for my physics-based game. The sandbox/editor is included with the full game on Steam, but levels are just JSON and I mainly use an external editor.

I wanted to share it here mainly to get feedback from people who’ve built physics tools or level editors before.

Happy to answer any technical questions if anybody has any.

Why would you link to basically a blank webpage. I dont even know what this is? Why would this blank webpage end up on hn frontpage? What is even going on here?

What I expect from my indies is love, care, and attention to details.

I hate to say it but I completely agree, don't want to be a downer I'm sure OPs project is cool, but I legitimately could not understand what it was based on this landing page. No videos, demos or details.

Came here to say this. Sounded interesting but website gives me no info

All of the level preview images show up as placeholder gray images that say 300x200 for me on iOS Safari. Not sure if it’s like that on all platforms and screen sizes, or just an oversight on mobile for example.

I assume this is a level maker for a game? A link to the game on that page would be great.
