Definitely a unique and interesting take on the theme!
It was really fun getting those souls delivered, and I loved how you added dialogues to make the game more lively.
The spirits getting angry and attacking the delivery guy was really funny, and one time that spirit said "Orange doesn't even suit you" and proceeded to attack me!
I really had fun reading those dialogues!
There was one problem I found, whenever I took the spirit from the box for the first time, the game would lag a lot, it even crashed once... but that only happens when you take the spirit for the first time, the game runs smooth after that.
I would suggest adding more obstacles to the map as the time passes just to make the game a litlle less repetetive
Overall an Awesome entry to the jam! Great job! (First try: delivered 11 spirits)
