Really enjoyed the game and recently completed 100% of it. My experience was good and I never had any crashes or issues.
After completion I was left wanting more. This is a good and bad thing.
I'm sure many of these have been mentioned but here you go.
Suggestions---
-Would love to have people being pulled by boats, wakeboards and skis.
-Sealife interacting with each other, great whites hunting seals, etc.
-Expansions to deeper ocean, more places to explore and more apex bosses (squid, larger sharks, etc)
-End game missions, tasks, challenges to keep us coming back for more.
-More human hunters, submarines, helicopters, etc.
-Cosmetic skins that you could use to change skin but still use some of the evolution pieces.
-I know multiplayer is off the table and would be a difficult task but maybe an end game coop? Can see a couple sharks tail whipping humans back and forth

-Increase progression, would love to grow shark another 3-5 meters.
Extremely fun game. I just need more reasons to launch it and have some more fun. Thanks!
