In the current design, combos and innovations are revealed little by little. Once discovered, a combo and the innovation it leads to can be checked at leisure in the Combo Codex (last choice in the main menu). It might change to a more open system in future versions.
AWESOME!!!
Also, Spin-vilization 2 should reach from Prehistoric Era to Future Era!
I'll give you suggestions, Palawa, Sentinelese, Anangu, and Inuits should be there also, along with ancient civilizations, ancient tribes, and all kinds of nations (like Mesopotamia, Egypt, China, the Indus Valley Civilization, the Roman Empire, Persia, Greece, Japan, the United States, the United Kingdom, etc.). Also, they should need flags as well. And also, I wanna see some cool aliens, if they are either hostile or friendly!
Also, please make it easier than the previous!
Also, I want to see if Spin-vilization would reach from the Prehistoric Era to the Future Era (complete with robots, flying cars, Dyson spheres, and more), plus I want a Kardashev scale as well!
:D
I would love to someday make a sequel that scales from Prehistoric Era to a Future Era ! But as for Spin 2, it will be much more modest. The reason is to keep the size of the project manageable for a single programmer, and to test new ideas. A small game delivered is better than a big game unfinished.
Also, considering the immense number of civilizations that could be featured, Spin 2 will probably only feature new ones, for the sake of variety. So Egypt, possible, but Palawa, unlikely.
I enjoyed making this game, so I'll probably do Spin 2 eventually, but I'm currently working on another game in order to raise funds for Spin 2. If you know other people who might enjoy Spin-vilization, you can help by telling them about it. You can also directly advance the project by donating. And anyway, thanks for your words of support :)
