This was a great little game! The title was genius and what followed after was really intriguing and fun! The way you made things start happening in the first night itself and then it developed more as the nights went as was really well done (Like the crack in the wall; that was a neat little foreshadowing for the end!) It was fun to play and the simplicity of everything elevated the story you were telling more so!
Also not sure if it was accessible, but there was a bedroom at the very end with a long wall connecting to the main house. It may have been an easter egg to show that there were others there, but it was a nice little addition to the mystery overall.
Great little game, it was really fun! Good luck on future projects!
