Fantastic! I don't think I've ever played a better "first game" before. Loved the whacky, sorta uncomfortable art style, reminded me of Cruelty Squad a lot, and great animations! Super unique. And it was really funny! The elevator scene made me chuckle. Had strong Undertale vibes to it. Well done!
My only feedback would be to (possibly, because it works fine without it) include a small interact popup, so you know when you're able to talk or inspect things a little easier. Could also be diegetic, like Pip changes expressions, shape or does a little dance to minimize UI clutter, which you've done an amazing job of.
