Cracked Ice

Is a vanilla-friendly mod that adds Cracked Ice (as the name suggests). At first glance it looks just like normal ice, but once you step on it, the ice slowly begins to crack until it breaks and drops you into the freezing water below.

Different entities affect the ice differently depending on their size and movement. Small mobs barely crack it, while heavier mobs, boats, minecarts, and fast movement can quickly make the ice collapse.

Frozen lakes are no longer completely safe — crossing them now becomes a small risk you have to think about.

Known Issues

Very large entity groups may cause faster-than-expected cracking
Mod compatibility with terrain/worldgen mods has not been fully tested yet

Bugs I found

The block is immovable with pistons (not intentional).
When riding a horse over the ice, it isn't breaking (only cracking, not intended).
I have v1.1.3, but it's still in very early alpha and contains other bugs that could break the world if you played v1.1.2, so for now these are smaller, less important issues than releasing an unfinished v1.1.3.

Parts of this mod were developed with the help of AI-assisted programming tools for prototyping, debugging, and balancing systems, but the original idea for the mod is mine.
