Hey thanks so much! Excellent high score. :D
Ah yeah I hadn't considered other keyboard layouts, just quickly whipped up the Input Map. I'll adjust in a future update, thank you for this!
So the color is in fact derived from a separate variable, but math happens sometimes. For the health I'm adjusting the blue channel when your health is over 50, to bring the silhouette to Yellow and then the green channel when it's under 50 but over 0, bringing it to Red. I've seen it go to pink when restoring as well, I think because the blue channel is going over 1.0, but that was such a B-level bug and I was running out of time so I decided to just leave it, especially as ultimately the health variable itself still shows Red correctly.
And there is a chair! Well, a bench, when you're doing the bicep curls. It was going to feature more prominently but my Buddy model got slightly corrupted in Blender when I tried saving it with multiple animations. Like, the outfit texture is lost, I'm getting Python errors when opening him, blah blah blah. Again, time constraints, so I cut the total number of exercises from 8 to 5 and left out the stretching animation. At least there's one. :)
