Thanks!
Yeah the gameplay was something that just emerged as I was making it and I didn’t have a chance to refine the UX on it, lol. The arrows are adjacency buffs/debuffs on the other cells (from the perspective of the building you’re placing/hovering over)
I’ve already got a change ready to deploy for always showing the descriptions and for showing a preview of the arrow buff/debuffs which will hopefully help with some of the confusion.
