This is my suggestion, maybe will make Raft more better..
- It will be good, if you can add the scenery like the one in the Life of Pi movie.. Such as fish swim around you, sunset, etc..
- Add objective of the game.
- Add beds, and Sleep system.
- Add more furniture..
- And last one, it will be good, if player can dive into the underwater. Such as, player can dive and see good scenery in underwater..
Thats my suggestion, just my suggestion. It will be good if you can implement it to Raft. But, if not, its ok.. I still love Raft!
