Having said that... this is mostly a slogan and makes for good Youtube videos, but it falls apart the moment you subject it to even the most basic scrutiny. For one... it doesn't make sense to talk about a speed through time since speed is literally a measure of change with respect to time, so a change in time with respect to time doesn't make any sense.
But as a slogan, it captures the idea that motion through space and the rate of your own clock are tightly linked together.
Only if you're talking about other people's clocks and not your own. Your own clock is one second per second, but someone else's may be slower or faster relative.
Some of the details in the paper are super cool. Since the game pulls "c" down to near walking speed, you receive photons at different rates depending on their direction relative to your motion (relativistic aberration / searchlight effect) resulting in neat visual shifts.
I don't usually download games, but I might have to make an exception just to try it out.
There is a helpful FAQ which explains all the weird things happening, such as length contraction, time dilation, and color shifting: https://testtubegames.com/srel101.html
