Yeah we should have invested more time into making the movement and mechanics a little smoother but I guess we got kind of used to it being finicky.
There are some interesting things you can do with stone blocks by either placing them on top of the NPC to push him a little or by blocking the line of sight to a ghost prop you placed to stop the NPC from moving. These mechanics aren't strictly needed to complete the levels but they can be incredibly helpful if used right.
Thank you for playing and for the feedback. I hope you still had a little fun playing the game. We are still learning and improving. Next year will be better. Cheers.
