Game Designer Jesse Schell says, that there are two kinds of themes in games. Experience-based (commonly found), and truth-based. Truth-based themes can be much stronger than experience-based ones, and little is required to have the theme resonate in the minds and hearts of players.
And Bring Me To Light brings, well, a truth to light. The game is so much given so little. The controls are messy, the level is tiny, the only music is in the ending, and there are several bugs and inconsistencies. But the truth, hidden inside, shadows all of these.
Also, the moth animation is great. 10/10
