I signed up to give it a try, but when I click "Go to Levels" it takes me to https://vimgolf.ai/levels and I get a 404 error.

same

but clicking on the hamburger menu it shows a link to “Motions”, which seems to be the first level/demo of the game

Sorry, yeah I am adding more levels, and will fix that! Thanks for testing!

This looks cool. Is it free?

Thanks, it is, right now! And will have a generous free tier once finished. The only big reason I am making a priced option is for users who want AI tips to be able to have that option. Right now, I do that by having reasoning models like o3 solve the levels and then provide tips or verifying a level can be solved with certain motions.

I'm always hesitant about signing up for services. would be great if there was a demo that didn't require creating an account!

I wouldn’t mind signing up without a demo if there was more information about what this is exactly.

Great feedback! Will role out a update with that information

Point taken! Right now I am exploring a way where users can test the service on the landing page, without signing up.
