Oh man. This perfectly encapsulates my fears of what working with other people would be like. (No wonder my creative pursuits have pretty much always been solitary or involved about one other person.) The ending seemed like a wonderful sarcastic twist on the earlier frustration - as if my character was about to start laughing with their development team, before they knuckle down and start brainstorming fixes, and actually make positive progress.

Edit: I played it again and apparently there's more than one ending. NICE.
