That was a fun little game with great atmosphere, sound design, and art. It was a fun challenge.
What does "less is more" have to do with the game though? I just took the souls one at a time to the center. Then I tried gathering them all at once and there wasn't anything different (though I died before I got them all).
What was the third ending? I died, got all the souls to the center, but idk what the last one is.
Overall, great job with the game and especially with your artwork.
