i've discovered a game-breaking bug with the ranger building. it seems you're not allowed to place the ranger building next to anything (which isn't explained in the tooltip, and presented great frustration until i realised what was going on in a second run. i would recommend explaining this fact to the player).
the bug: if you place the ranger building down, you can then place other buildings within its no-buildings area, at the very least houses, doing so utterly breaks the game:
the ranger building's little circles (which indicate connection to a forest) remain eternally highlighted. the offending building can't be moved. in fact, no placed buildings can be moved at all.
further, choosing "begin night" begins a night with no enemies. the night "ends" correctly, in that money and choices are rewarded, but the night counter doesn't advance. the first time this happened to me was exactly on night 5, so i kept getting torches and one extra reroll, which was very funny.
i played in this enteral night 5 for a while, placing torches to expand my area and upgrading methods of acquiring money in order to level up faster in order to get more upgrades. the eternal night 5 never ended, and i got bored of waiting for the bug to fix itself. at this point, i didn't understand the cause, and assumed it was a hiccup in the night counter.
the second time the bug happened, i understood the cause was placing houses directly next to a ranger building. this time it was on night 10 and i kept getting 1 extra choice (the dialogue still said 4, but i had 5, then 6, and then they went off the screen). i still couldn't move any placed buildings, enemies continued to not spawn, and the night counter didn't advance.
that was probably more detail than you needed.
besides that, this a very fun game! i made it night 19 twice but have yet to survive 20.
EDIT: oh, i'm not entirely sure if it's a bug or a questionable UI choice, but i've found that when placing buildings they appear in my cursor in a different position (a little higher) than they will when placed. this makes trying to place things neatly rather confusing, and requires trial-and-error for things like linking up towers with barracks.
