Thank you so much! I'm really glad you enjoyed it.
If you're curious about the Unity side of things, feel free to reach out! I had a lot of fun implementing some of the mechanics for this jam and I'd be happy to talk about how they were put together.
As for the cages, they're actually meant to capture the spirit/light. The player character can still move, but without the spirit's help they'll eventually fall (or at least have some "hard time" finding their way). It sounds like the mechanic could use a bit more clarity, so that's great feedback.
Thanks again for playing and for the kind words!
