It's probably a result of the way my trackpad drivers handle events, but I couldn't grab and hold any of the toys by holding left click (just treated everything as a click so the toys just flew around whenever I tried to interact with them!)
Nevertheless, the physics and collision handling looks to be well implemented, and it runs very fast, and it's definitely on theme.
Unfortunately, that's kinda all we could do as we were implementing these mechanics as the last things. Also, it all runs on Jolt Physics, and since it was the first ever attempt at using Jolt for both of us we couldn't figure out much in time how to properly manage the control of the objects, so they just fly away (well actually they try to stick to player's POV but tracking is broken)
