Q:

bash: ./WorldOfGoo.bin: permission denied

I tried to launch World of Goo from the terminal (./WorldOfGoo.bin), but somehow I couldn't launch it. 
It displays the following error:
bash: ./WorldOfGoo.bin: Permission denied  

Can anyone help me with this?

A:

Make the file WorldOfGoo.bin executable first, using the following command in terminal:
chmod +x WorldOfGoo.bin
