Looks good to me however I don't think those sprites fit those tiles. Find it funny that the doors are giant to compensate for their height
Good luck with your project @Refur, I hope you stick to it

You need to create a stackable item for arrows.
You need to create a arrow projectile assigned to that item.
You create a weapon item and set the projectile to be the arrow projectile you created.
That's great! 3-4 months is a Long time I'm glad something I work on has left a mark on you and I'm always Glad when my work inspires others, especially in the communities I spend time in.
