Thanks for taking the time to comment, I set the traps and barrel explosion base on the special notes of the tune (this is why it pauses when you die :). I have been told my jump scare trap does not feel aligned to the tune which i suppose is to do with the animation length. Music is not a strong area for me leading me to this concept - in my head i had many more trap and actual enemies utilizing the special note but sadly met my limits.
As far as the not picking up in the dark, this was a conscious choice with the goal of showing the importance of the torches and lighting the wall and floor torches to allow easier navigation when the player no torch.
Thanks so much for playing and providing so much valuable feedback :)
