This game does not feel like a finished product to me. please read below for why I think so.
This is a pretty good game, however there are quite a few flaws that become evident late into the game as well as after the story mode.
I would still maybe recomend this came to some friends, but not without going through the issues with them.
-I completed the game in both adventure mode and the more challenging "survivor" mode without dying once, it was way too easy. Maybe add a difficulty setting other than spawn control in only the sandbox mode?
-I never used late game equiptment at all, it's not even needed to dive to the deepest part of the ocean and win the game.
-Once you get to the deeper parts of the ocean, the noise starts getting all buggy and you can't hear enemies anymore as well as other sounds that should be there.
-There is virtually no late game. The bottom of the ocean is actually easier to survive in than the shallow area you start in. the late game boss enemies don't even attack until provoked.
-While there are some cool things you can do with building, a small two room base will do you just as good as a massive fancy base.
**and finally my biggest problem with this game**
-During adventure mode you earn money to use in the sand box mode for free play. Okay, awesome. However you can only use this money ONCE, for ONE sand box game! After completing the adventure mode and Survival mode with gathering as much money as possible I started a sand box game with everything I wanted :) And then I tried starting another sandbox game, with no money to actually start with anything... So to play sand box and actually have enough money to start with the fun items you have to spend hours in the regular game -_- each time...
There are a lot of things I find annoying with the game play. But you know what? I still enjoyed my time playing this game. It just doesn't feel finished. It feels like this game is still in production.
