I made it alone in two weeks. The scope of a game jam is not to make a finish game but to experiment new gameplay, designs, moods, ideas. It's terribly exhausting just to make a game in months. Here I made a whole city district, the 3d models, textures, shaders, level design, code. You have to realize stealth games and AIs are also very time consuming.
I see no point coming and insulting me after I offer you something free to try.
