The art and music was fantastic. I am not the greatest fan of these kind of stress games, and in the later stages it was impossible to make sure all the houses were haunted. Which I thought was the goal of the game, yet failing to haunt a house didn't seem to cost me any life, and I succeeded in my first game. It was... a weird experience.
There were some issues. The HTML5 version seems to not scale correctly with my screen resolution, making the game unplayable. Luckily the Windows version worked. Also in the game, sometimes a ghost would get "stuck" on a hauntable house, because if I clicked the ghost, it instead showed my haunt progress. Also, the movement of the ghosts were a bit inconsistent, and I sometimes had to instruct multiple times before one would move. But those issues were minor things.
