A dungeon generator, but since there are so many of them called "Dungen", this one just sounds like it.
To install Donjun, clone the repository and use dotnet to compile:
git clone https://github.com/xiaoxiae/Donjun.git
cd Donjun
dotnet build -c Release
The binary can now be found in bin/Release/.... To run, simply do ./Donjun, possibly with a --help parameter to see possible options.
