This mod is an update and enhancement of Sovereign's Simple Ice Blocks mod for Rimworld 1.3. The original mod added craftable Ice Blocks which could then be used to build all sorts of things, namely buildings. The original mod had a focus on being a simple XML mod. For my update, I wanted to enhance building with ice by adding a challenge: ice melting. This made the mod less “simple” by introducing C# code, but I think it's a good change that encourages Sovereign's goal of Ice only being used in frozen biomes like Ice Sheets and Sea Ice.
The goal of this mod is to add a new resource that can be easily obtained on Ice Sheets and Sea Ice. Given that these are intended to be difficult biomes to build a colony in, this resource is intentionally designed to be the weakest choice of them all for general construction. It's fragile, can only be obtained in these biomes, and can simply melt away if it gets even somewhat warm causing problems for the colony. However, it does provide a building resource that could be useful when there are no other options, especially on sea ice colonies.
