For the players that merge 5 at a time, sometimes it gets difficult to find the space for all the crates used and the plants/animals/etc. that come out of them. Just a thought, maybe introduce a way to "trash" or store items to merge later. Like a supply sack or barn that items can be dragged and dropped into for use later. If someone wants to save keys to merge later, then this would give them the option to save them without taking up a square, in turn that square could be used for another item. Ultimately the "map" can get rather crowded with merge items, so just a thought on how that can be improved! Otherwise a very enjoyable game
