One of Them was a game for the Wowie game jam in 2018. The theme was "everything interacts with everything". The main character, Mina, is posessed and building up demonic energy which will kill her if it reaches max, so she has to release it by interacting with the trees or rocks, which will turn into a demon version of themselves. These versions hurt both Mina and the monsters lurking in the woods. Mina has to find her teddy bear, which is only visible when the flashlight is on it.

We had planned to make this into a full game, with a town, a story and characters to interact with, but the project was put on hold indefinitely due to time restraints.
