I am suggesting to allow datapacks to be able to modify gravity, air resistance, water/lava buoyant force, and block collision box sizes. This would allow for way more customization with datapacks and having more control over how krunch handles your modded blocks Krunch would be able to treat your 1 pixel block with a 1 pixel collision box and not a 1 block collision box.

(I can’t access vscore to suggest this and there is no feature request template, so I’m doing it this way)

Even if the block size got excluded, datapacks would be much better from this.
