I recommend this game under one stipulation. You buy it for a 1 hour experience and do not expect more than than that. Treat this game like "They Breathe". Not like an action platformer.
The sensation of being trapped at the bottom of a sinking ship. The utter seclusion and panic you feel as all is falling apart around you. These were real emotions that I felt during my first half hour playthrough of the game. Then I went in for a second time and wasn't nearly as impressed. The following is a list of problems that hurt the experience of this game.
1: Rising water should cause players to feel a sense of panic. Unfortunately, the water is almost no threat to you as you are given plenty of lung capacity AND you can find plentiful air bubbles. In fact, there were a few occasions where I actually waited for water to rise so a platforming section would be easier. So the main enemy of the game is a flop.
2: I can't explain what's going on with this start screen menu. Sometimes it slows to a near hault and doesn't let you input anything, forcing you to reboot the game. (I did this three times in a row and the same thing happened). Sometimes if you let the animation in the background play for too long, the same thing will happen. I just don't get it...
3: The start menu music is very good and conveys a sense of foreboding, but the music that plays during the game I find very repetitive and unappealing.
4: The majority of the game seems to indicate that the devs were going for a serious experience. If this is true, then why are most of the radio transmissions trying to come off as humorous? Not to mention they keep coming up and stopping you in your tracks until you finish the message; Castlevania 2 style. This can be avoided by just not getting the radio, but with darkness covering the terrain most of the time, it's easy to pick it up by accident.
5: I actually like that there is no pause button in the game. It helps to convey the urgency of steadily sinking to the bottom of the ocean. I would like to believe that the devs made that choice on purpose, until I discovered that the radio transmissions pause the game when they come up. *headdesk*
6: This is more of a personal issue, but where does this game get off having so many trading cards to unlock? Not only does it take around 14 to craft a badge, but the 7 that the game gives you for purchasing it come at such a slow rate that you'd have to play the game for around 5 hours or more to get all of them. Sorry devs, but you are just way too big for your britches if you think people are going to play this game for that long.
Like I said, buy this on sale one day or in a bundle and enjoy the experience for an hour or so. Maybe you can find enough enjoyment to play for longer, but I found myself putting the controller down after 3 playthroughs. I don't regret playing the game, but I do regret that it isn't better. This could have been something truly memorable.
