Very cool game! I was really impressed right from the start. The game onboards the player perfectly and it is really fun to play. Also really good work on the controls!
I like the art style and the music fits perfectly. Also it is really helpfull that you highlight the body the player is going to possess. This is really helpfull once the bodies are close to each other.
But I also found some bugs:
1. there is one level (don't remember the number) where you have to collect 2 keys. If the player collects the keys first then he can't win the game. Because the first door consumes both of it.
2. in the level where the wizard was introduced I couldn't reach him. Once the armored one was on the spikes in front of the wizard I couldn't leave this trap. So I decided to not go for the wizard at all.
Also there are some levels which have more bodies than needed. Or another level had 2 keys but only one keyed door. I tried to find an easter egg but not sure if there is one.
But bugs can happen (specially in a jam). One thing you could add to the game would be a "replay level" button in pause-menu and when the level has been completed. I would have made use of it :-P.
Overall a really good game! I enjoyed the puzzles and had a lot of fun with it. This game definitively deserves more ratings!
