The game is not a masterpiece and a lot of models, textures were found on the internet. But the idea and the gameplay was made by nightcoffeegaems.
The idea came about 5 years ago. I've moved from a smaller town to a bigger one. I was renting an apartment on the 12th floor. Every morning and every evening I've been riding an elevator. Twelve looong and boooring floors down and twelve looong and boooring floor up.
