It's kinda glitchy-I got to the treadmill test and then it just kept repeating text boxes.
I did download it, to try to make it work better, but no luck. (Windows here.)
It looks decent, though!
It's been hotfixed, but I didn't upload the build because I wasn't sure if it breaks anything.
If you move away from the treadmill before you press space once you finish the sequence, it won't start it again. If you use mouse clicks to skip dialogue and don't accidentally click the treadmill it won't start it again.
