Thanks for the feedback! :) Yeah you're right, there should have been more clues for the player. I was working on a playback feature to see how a run played out but it didn't make it into the game, which would help analyze what happened. I'll update the game post-jam when the rating period ends. We have a little hint that says the monster teleports away to safety after killing, but it's not very noticeable. We should also add that the monster does not kill while it's in the light. I'll update the description with some hints for now.
Thanks for playing, I hope you will get some enjoyment out of it with some updates :D
