Cloudpunk is a pleasant surprise. The visual effects are stunning (for those who like such visual style). The freedom to walk around that city and freely explore it alone would make it worth it. Voice acting and dialogues are very good. It has many references to other games and movies. Sometimes it might get slightly boring because the gameplay is a bit limited (just going from point A to point B, talking to people, interacting with objects and exploring), but the plot progression ends up paying off and, as it is a short game, it's not that hard to handle some repetition.
I could go wandering around this city doing nothing. Just for relaxing and enjoying the view. I'll probably do that in the future, I actually missed it after finishing the game.
