Which browser are you playing in? For me I find it works smoothly in everything except firefox mobile.

Testing this on a Macbook Pro M4 Max, dragging is still so choppy that it makes the game significantly less fun.

Which browser are you playing in? For me I find it works smoothly in everything except firefox mobile, and I'm just on an M4 Air, so you've got way more compute.

This should be fixed now.

Would be interesting to see if it was logging hard to the Web Inspector console.
