This honestly needs some fine-tuning. The idea is pretty cool, but I really wish it was executed in a more cooler way. One example of fixing this game would be to make the X button in random locations for each playthrough. It's simple, but it would definitely add more replayability to this. Another example would be a quick-style game where you could close as many windows as possible as fast as you can. You can honestly do whatever, I just want to see this idea fully realized, because I find it personally cool.
