Really loved this game!
The game-play is so much fun, although it's also quite hard and as I'm just terrible at these kinds of games I don't last for too long. Still I really enjoyed trying it out.
Regarding the theme, the game is just marvelous. The art-style and music, all fit really well. And I really like the idea of light working as a sort of mana for the protagonist, also along with it changing your field of view as you get more or less of it.
Overall, a really awesome game, many congratulations to the whole team, would give it extra stars if I could.
