Really cute game, art and sounds are great! I love the mechanic and I feel like it has lots of potential with even more soul types! Maybe even make the way the souls behave necessary from time to time? (like you need to use them to smash through walls). But yeah, really excited for what you do with this!

One thing I will say though is that the spikes and spinning saw blades made me think my character was going to get killed! But in reality, they just do the same speed reduction as all the hazards, right? I would recommend having hazards that look like they will effect the player the way that they actually affect the player (eg. a saw looks like it will hurt/damage/slice the placer, some thick slimy goo on the floor looks like the player would get stuck in it and slow down).

But that's just nit picking, overall nice entry!

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)

Pretty neat take on the tethered together mechanic, it's cool that the other entity being tethered is antagonistic! The music sounds great and I love the little voice sound effects :)

One possible idea to try might be a risk reward mechanism where you can pick up multiple spirits at a time but there's a tradeoff of it being much harder to control.
