I always love seeing odd frameworks and in-house tech. I'd actually never heard of Panda3D before.
I'm personally not a fan of the style- I found the characters pretty ugly and the environment not much better. But it's clear that a lot of thought and effort went into the modeling, and the animations are smooth and appealing.
The intro cutscene was cool, and does a pretty good job as a hook. I did find it hard to tell who was talking, though, and some of the text was cut off.
How complete did you consider this project? It feels maybe halfway to me. There are a lot of interesting movement mechanics to try, a decent section of world, but also it seems some of the interactions aren't working and it's unclear where to go once you're dropped into the world. I did have fun tooling around and playing with stuff, though.
I found it really awkward to play for a few reasons. The movement mechanics are super cool when they work, but I often found myself drifting in random directions, just not stopping, or getting stuck in one mode or another. It's really hard to judge depth for some reason, which makes platforming sections difficult. I also found the controls awkward, but I think with time I would have gotten used to it a bit more.
The game runs horribly on my machine, although I understand it's a known issue (Windows user here).
Finally, is that the presidential seal hidden (?) in the map?
