How to build the codes of Amaranth

[moba]

(Excuse me, but there may be some rude expressions because of my not good at English.)

Hello. I'd like to build the source codes of Amaranth, an roguelike game. I downloaded the source codes from GitHub. Here:
https://github.com/munificent/amaranth
But when I opened Amaranth-2010.sln on Visual Studio C# 2010 Express Editon, it told me there were two files which weren't found:

'Amaranth.Terminals.csproj' and
'Amaranth.Terminals.Test.csproj'

So I couldn't build and run the source codes. I wonder if you could tell me the way to build the codes of Amaranth.
Thank you for your reading
