A general set of suggestions I came up with that maybe might address Aquarion's balance issues they currently have
- Allow roads on flooded tiles
- Allow mermaid styled units to use roads
- Make tiles not flooded by default
- Allow to flood tiles within borders as an ability (costing 1 star? 2 stars? Automatically? Not sure)
- Make flooded tiles block movement similar to forests for naval units only
- Allow more than 1 atoll per city
- Give Yelly Bellys 3 attack
- Allow both flooding (with units) and filling tiles to be available after moving
