The city looks really nice, the little construct animation is great too. Gameplay wise I really struggled to understand how to put things down (it's not that obvious that the background layers are actually walkable as well). Now that I figured it out (I think), I still sometimes can't place a ladder where I want to so I'm a bit confused. I may be dumb but I think some feedback (gizmos to show where things can be placed, or cursor changing, etc.) would help a lot here.
