Thanks for the feedback! Glad you enjoyed the game, and the character.
The spider quest was meant to be an absurdly difficult easter egg hunt, but yes maybe overboard.
Since you're one of the first people interested in finding them all, I'll give you some hints:
SPIDER 1: Somewhere nearby before feeding Bat-Son
SPIDER 2: Outside puzzles as early as possible
SPIDER 3: A long dark tunnel after Husbano's advice
SPIDER 4 and 5: Above and below after finding Bat-Son
SPIDER 6: Some fresh air after statues vanish
