Programmer here! Thanks for the kind words!
With regards to the arrows, its totally possible to pick up enormous quantities of arrows all in one go! Two of the houses spawn arrows every 8 seconds - we forgot to randomise their location however! This would mean the arrows only appear as a single sprite, which is "effectively" a pile of sprites in the game world. And since the world persists between runs its highly probable you walked over said pile thinking you're only getting a few extra arrows!
