Thanks for playing! We appreciate the feedback. Yeah, I forgot to remove the jump, it's part of the template for a character 3D movement. I wasn't sure what features we were going to have time to implement and just forgot to remove it. The first part doesn't let you get past the gate unless you have the map, there is a LARGE part of the map that you shouldn't be able to get to unless you jump over the wall and there is no way back, you're basically soft locked at that point.
If you save all the souls, there's a key that opens the second gate. It doesn't take very long to beat and there's no loop that you should hit unless you didn't save the one near the map or by the gate then you do have to come back. The key is a bit small and hard to see on the "map." There's no map, it's a camera view from the sky.
We did have sounds for the ghosts and we had story for the ghosts and souls to save, we just didn't have time to implement and test before the submission time.
