I wish I could give a "neutral" rating to this game, because I cannot in good conscience say "yes" or "no" without a lot of caveats.
First, I have played the game for abut 9 hours thus far. It's lovely, the gameplay is fairly smooth, and the ever-present battle against the air tank adds a little suspense, particularly before any upgrades are peformed.
However, the game plays like a beta - there is very little content or diversity. I love a good survival/hoarding game, and this should fit the bill perfectly; however, the extremely limited crafting and resources are disappointing.
When I purchased this, I thought it was a beta, and I continued to think that until I sat down to write this review and saw the others. It's very sad the devs are done with the game, as it could have a lot more added to it.
Things I like:
* Novel concept and storyline (thought it's far too short)
* Beautiful, rich, underwater environment
* Automated defenses, like drones and turrets
* Extra cargo space with drones
* Exploration which requires upgrades to complete (though it can all be seen and done within a couple of hours)
* Increased danger from predators at night
* Upgradable equipment
* Automated resource extraction
* Decent hunger/food system
* Blood mechanics (blood in the water from injuries or hunting attracts predators)
* Music and sound effects
* Decent world topographical map showing major points of interest/resources
* Decent agricultural system (but it would benefit from more options)
Things I dislike:
* Terrible gravity system - I understand we can't just have the ability to limitlessly ascend, but the current system is infuriatingly limited.
* Limited crafting - number of possible objects/upgrades is very small.
* Limited construction - More base options would be nice.
* Storage chests are far too small and non-stackable.
* No way to recover items after death - at least none I've found.
* No way to sleep through the night to fast-forward
* No way to split stacks in inventory at all - at least none I've found.
* Some items are ridiculously expensive to craft/consume for the reward.
* No ability to save the game without quitting.
What I would like to see:
* More diverse predators
* More storyline
* More biomes to explore
* More craftable items
* More and better base construction
* More discoverable points of interest - different wrecks, caves, et cetera
* More resource types
* Less expensive cooking - each item of cooked food takes 1 coal, which can be difficult to find
I got this on sale for less than $5, and it was definitely worth that amount. I might even say it's worth the $14.99 if you're the sort of person who doesn't want a seriously challenging game, and are more in the mood to mindlessly (in a pleasant way) gather resources and live out your life on the ocean floor.
Still, it could be so much more. I hope the devs might revisit it at some point; however, if they don't, they made a very nice (albeit short and very limited) and interesting distraction.
