itch.io

Just opened it. Everything was fine for me.

Although I had to install the correct unity version first.

Well It does not get called less, it just gets called at constant intervals. Every Physics step is calculated in fixedupdate. Since you try to do a physics call it should go in fixedupdate.

In normal / late update the call interval can vary depending on the framerate thus a collider may not be correctly moved according to phyiscs yet.

I fixed it in Day 2.
You put it in LateUpdate but it should have been in FixedUpdate.
