It functioned for me correctly for me... Extract the project and double click the "crazy penguins" application (with the unity logo). Once you click play hit the spacebar and after a couple of seconds the dice will land causing the UI to update. Once you see a number press either q, e, or r to place a block. Once placed you should only be able to place one block. Reroll the dice to get a new number and repeat the process. Hope this helped! If it still doesn't work do you mind sharing your computer thanks.
