Thanks for playing :)
Balancing the tools, The Entity's speed, and his aggro timer were definitely some of the worry points for me, so I'm glad you liked it lol. I feel like I should have used more specific words for the tasks because I know how everything works already, but other people don't lol. (there's probably a term for that)
SPOILER (if you will), to bait The Entity into the rune, you must let him attack you in the darkness and make sure he runs into the rune before he reaches you. :)
