For a good introduction to developing an intuition about special relativity via low speed of light, I really recommend George Gamow’s “Mr Tompkins in Wonderland” (or “in paperback”). These short stories explore things like how the world would look if the speed of light were 10 mph.

There was once a flash game that integrated principles of relativity into its mechanics for teaching purposes. It was a series of 2D rooms with the goal being to move from point A to B. I remember there being changing distances as well as colors, for example moving a certain way would change the color of a lock so that the key of that color could unlock it. It was good fun, and it was written by a physicist and hosted on a humble personal site. I can't remember where I saw it, but if anyone knows the reference, please share a link.
Another game in this vein of "teaching math/physics through gameplay" is Hyperbolica, where you explore a 3D world with hyperbolic (and later spherical) geometry. It's mind bending.<p><a href="https://store.steampowered.com/app/1256230/Hyperbolica/" rel="nofollow">https://store.steampowered.com/app/1256230/Hyperbolica/</a>
What would happen if say you were traveling 1 m/s and the speed of light was 2m/s?<p>I imagine there has to be some special properties when youre at exactly half, or some other special ratio of the speed of light
