The Adventures of the President of the United States is a funny game you can play in 15 minutes. It's highly caricatural and can remind of some old point n click adventure games (you can travel through various countries with just the normal compass directions). Some puzzles are not hinted enough I think, and you have to carefully examine everything to get new clues and open new possibilities.
I didn't manage to finish it though, even with the walkthrough, because an object I was supposed to get wasn't at the expected place (Spoiler - click to show)(the opener in Russia), so I suppose it was just a bug (maybe replaying it with a different configuration may solve this).
It was enjoyable and diverting anyway.
