That was very creative! I enjoyed how you implemented the topic. And goblins are just adorable :)
I must admit I got a bit tired of clicking the buttons to get back and forth into the programs! Maybe it would be helpful to have fewer control options or easier ways to open the programs, as the main challenge (how to beat the game) would still be there. Right now it was a bit more of "How to beat the controls" for me :D I also thought that I do not install the game as after you click "Yes" there is no indication that it is installed. Maybe some sound would be a clue to check your desktop! And there is "Space/Enter - Confirm (Menu)" in the controls list, but I only could use space to enter the game.
A solid game! And thank you for the guide, that really helped to get on the right track :)
