This is an amazing start to a game. I love the idea of using the out-of-body experience as a puzzle mechanic. The lighting system with the art style in the game blew me away.
In terms of gameplay, puzzles are interesting but maybe a bit too easy. I love the idea of using the out-of-body experience as a puzzle mechanic, especially with the last puzzle.
With the other characters, it would have been nice if you could have continued the game without the main monk. Maybe for polish, you could prevent the character from going onwards as I tried this and got stuck due to lack of lighting. Also, sometimes the ghost would overlap the character you are playing as.
Otherwise, it has become one of my favourite games from the jam, well done.
