game it's realy fun but mobs hordes are too fast and too big on early game i think its should be more settlers or posibility to find or make aditional ones some beter posibility to defend isle(some turrets) and making it biger or posibility to atached smaller islands, change to biger dmg to settlers
Game is released as is and development is not going to be continued. This was stated clearly in the description.
Defending the island is quite doable with just the 4 settlers by building and manning towers. Just see the various youtube videos posted in the comments.
