Fun idea! Hehehe.
I got confused for a few reasons...
I was trying to nail the picture to the wall, but I think the nails spawn out of the nailgun a bit (too far) in front of you, so I never saw a nail... I guess they were appearing thru the wall, then shooting forwards.
But hey, it's my first day on the job! I just can't get the hang of the job, dog gawn dang it. Dunno how to use my nail gun. All good.
I finally got into some "trouble" with my boss, and then I just wanted to get into more trouble as things escalated!
So I was a bit disappointed when it ended. I wanted to go out in a blaze of extended glory. ;) Hehehe.
Nice work!
