Sorry, just had another really good question aside from looking for the soundtrack! This game was super good, do you ever plan on adding more to the game? Potentially Cameras for the Basement Hallways and the Hazy Maze Room? I would LOVE that as a harder difficulty option! Sorry if two comments was a bit much!
I thought about adding either more levels from Mario 64, or even other N64 games, but currently I don't find the time to add more.
Adding difficulty to these scenes is a challenge since N64 games generally have fairly simple or empty levels, so it is often quite easy to notice when something changed.
But I think it's okay to have an easier Observation Duty game compared to the usually very cluttered ones.
And don't worry, comments are always welcome!
