I really dig this game. It took me longer than it should have to realise that you can move and delete tiles, which would have made a huge different earlier on (but I guess that's on me for not reading tutorials fully...), but I managed to get up to village before realising.
I don't know if they're meant to work like that, but it seems like research tiles like Causeway and Glacier say that they should synergise with themselves as neighbours, but end up providing +0% benefit to any of the tiles of the same type. Is that right, or is that a bug..?
