Hey I'm the original developer of this, I've since lost access to that account. I can say this was my first game made with the Unity game engine, so I really didn't know what I was doing back then. For the game to work make sure you download both tetrick the game.exe and tetrick the game_Data.zip. After that extract the zip file, place the exe inside of the folder created from the extracted zip, and double click the exe to launch.
