Life is strange is one of these games that is focused in the history and you made the decisions that will build the history.
Besides being an awesome, immersive and "comfy" game, life is strange also carry within a message: "What's done, is done". And you ask me, why?
In the game you have the hability of rewind the time, in other words, you can return into time if you don't like a decision you've made. That's the great thing, the game gives you the sensation that you can do everything perfectly, that you're powerful, but in the end of the game, when you realizes the tornado is caused by your rewind hability, you feel like your world is in ruins.
The protagonist is a ordinary person, like most of us, we would love the hability to rewind time, but it's "impossible", and the most important, even if you don't like the consequences of your decisions, you can't undo anything, that's the sad reality, but we can do nothing about it.
