Thanks for trying out the game!
I kinda understand where you're coming from. When I was planning the game, I wasn't sure how to damage the player but I decided to make it so that the player gets damaged by light sources during Daytime and the player gets damaged in the shadows during Nighttime. I also designed the levels where some parts can be passed through during a specific time so players will have to swap do Day or Night. Still, I'm glad to hear that you still found the game nice :D
