You've done really well at tying the feel of this game together. The music, style and nature of the game all fit together well.
The gameplay is easy to pick up, and offers enough strategic thinking.
It does feel as if i'm "doomed" to loose :), as there's Never enough torch battery, even with spending the gold i pick up. But it gave it an extra sense of urgency about how the light is used.
And for your first game as well! Really well done! Nice fun game.
