Hey, my ideas for this game are as follows:
- Add weather - such as wind, rain, harsh sun, cold, cloud
- This could also impact how much resources drift in
- Will alter how the players health, food and water change
- Will likely need clothes, or shelters to combat this
- Day night cycle (others have mentioned this one already)
- Also beds to recover health, at cost of time and food/water
- Time progresses - potential for bonuses
- A story line, or back story about why your on the raft, and where the debris is coming from
- Challenges/achievements
- Different AI type sharks, multiple sharks
- Other enemies/dangers
- Bad things drifting by - bombs, flaming oils, large logs
- Reinforcements for foundations, defense based tiles
- Visuals for damaged foundations when not holding the hammer in repair mode
- Craftable powerups which increase good debris, or decrease bad. or impact status change from weather or other, increase or decrease enemies
- Throwing shark meat into the water scares away the sharks for a short duration, or a craftable repelent
- Islands which you drift past, but if you hook them you can explore them for a possible bonus, but traps and wild animals are prevalent.
- Tech tree of resources, farms, weapons, character traits etc
