Demons is a game me and a friend made for a small school assignment, where we experimented with triggering emotions in players through mechanics and play.
We aimed to make the player feel stressed and on-edge, and did so using our light system in our game.
I went a bit more in depth in my devlog, which you can read here.
The game is available for free, so give it a try if you've got some time. We'd love some honest feedback.
