Very nice atmosphere to the game, I found 6 soul before the spikes got me but it plays and looks really nice. I don't see where the theme fits in, you could argue the more souls you collect the stronger the light gets but I didn't see it.

Thanks for playing! Glad you made enough progress. So in terms of fitting the theme, as you progress the light gets stronger so you see better, the FOV increases showing you more of the map at the same time, and your speed also increases.
At the same time, the spikes also become more and more as you progress (from 1 at the beginning to 4 near the end), the seekers also become more and move faster. So in fact I tried fitting the theme for both the player and the enemies.
But I understand it might be subtle, so I do not expect to be the best game in theme votes.
Thank you very much for the feedback!
