We combined a city-building simulator and crafting alchemy game to get an interesting turn-based strategy. In this game, you do not just build buildings, but change those that are there into the ones you need, spending and receiving resources.
Each building can be obtained from several recipes and used in a number of recipes to obtain another building and/or resources, including units and other valuables. Thus, the same building can cost different amounts of different resources and require different amount of turns to obtain.
You get new building foundations by dropping matter (resources) into the rift. If the resource was one of the marked ones - you will also get research points progress.
Be careful, the more you interact with a particular building, the more fragility it accumulates and can disintegrate if you are not careful and do not take care to reduce this fragility.
The core mechanics are built around combining resources and buildings.
Put resource {2} into building {1}, it transmutes into building {3} and resource {4} is created at the moment of transformation.
The recipe shown will not work instantly but with a delay of one turn {5}. The resulting building will have more fragility than the original {6}.
* - How many buildings and resources of the specified type do you currently have
As you progress through the research map, you select building variants with different recipes and capabilities. This way, each run will be different.
