Full review (as it doesn't fit on the page)

[Ukin]

I used keyboard and mouse and it was ok.

Pros:
* Nice chill game to simulate diving.
* Game could have a potential if story would written better.

Cons:
* Game feels unfinished (see below).
* No deep waters or caves (except ice level).
* Intro is unskippable.
* All cutscenes are unskippable.
* If you Alt-Tab for any reason during cutscene, you may require to restart whole game as cutscene will never finish.
* Items are repetitive and player would search basically for only 4 items in a whole game. Other items were lately added into the story, but they’re not quite interesting. The only level with trash is described below.
* You’re in danger! Touching any surface and even bubbles will hurt you.
* Sharks wouldn’t live in contaminated water, as well as fish presented.
* Your oxygen is your health.
* There's no help or suggestion system to find that last collectible.

Unfinished:
* That guy talks all the time about money, but there’s no feedback that any items, shells or trash that you take are worth anything. It seems that he takes all the money and provides you only with fun of diving.
* Locations are empty and shallow. There’s a level meter, but it never felt like I’d have any challenge or deep waters. The only level with some challenge is the ice level.
* Ice level intro features some unknown danger inside, but nothing is there.
* There’s only 4 or 5 kinds of small fish and about the same of sharks.
* No animations for picking stuff up. At least some progress has been added, but it feels redundant in this case. Simple grabbing animation with arms would be nice.
* Most of the tools are required once or twice in a whole game.
* Leveling system is cut to be basically redundant. It would be better if there were points for levelling and user would be required to take desired abilities.
* One level features trash instead of shells, which could be nice message to keep our water waste-free, but idea probably has been scrapped eventually and became redundant.
* Healing fish is ok, but there’s no story behind it and it’s just another collectible after first half-level. It mentioned only once when you take a gun.
* There could have been at some point an idea of selecting and changing equipment on the shore, but probably it has been scrapped if it was there at all.
