Here is one for if you have absolutely nothing better to do. Escape From Aqua is an online game with the object to get out of an apartment in the Aqua skyscraper in Chicago. It’s a straightforward puzzle game where you have to collect items and find clues and make those work in order to find a key to get out. Not a masterpiece game but hey, it involves a skyscraper so we’ll give it a mention. The walkthrough video takes 13 minutes so it probably would take me 13 hours to find my way out. Screenshots below.
