Is under the ocean worth to buy?

Well, the developer gifted the game to me many months ago, and it sure is a lot of fun IMHO. So yeah, I'd say it's definitely worth the money I invested in it.

It's early acces, it's cheap, looks great. What's the problem?

Its unlikely to get cheaper anytime soon. Its still being developed, so the cheapest you'll get it is in a bundle about a year after release (which is still a ways away). I'll probably end up getting it during this sale to play once it gets finished, or at least closer to being done. It seems like it has a ton of potential.

Definitely worth it. It's alpha so it has bugs ofcourse but it gets updated frequently. Even though it's still alpha I sunk 5 hours in it and enjoyed it despite the bugs.

I think it's really worth buying game. It's really cheap now (-75%) and have the most important thing in games in my opinion - great atmosphere, even better with great music. It's still in development phase so they will even add more features in the game later. So... I can definitely recommend that game. Actually it just depends on your taste in games.

I will wait until comes to a bundle >:) for 1$ :D

Its still in alpha, it seemed promising enough for me so I bought it. $2.49 is a good price too.

Get it. It has a couple of annoying bugs in it, but what can you expect from a game thats still in alpha? Still a good game without what the guys are trying to accomplish. I almost feel guilty for buying it at sale price.

I don't like it honestly. I find the whole UI annoying as fuck. Then again it's still alpha so who knows what will happen in the future. Still, it's pretty cheap.

I bought it for 1,24 eur. Thanks for all the comments, I won't regret it. :3

Don't know why but when I see "under the ocean", it reminds me Bioshock 1. Never heard of this game, will check this game out.

It's good enough that I bought it early even before steam summer sale started at full price of $7 from their developer.

I've won it here xD
To be in "early alpha" seems pretty good

I posted about it in the Hidden Gems thread here on SG.

I also added my first impressions on Steam: http://steamcommunity.com/app/227720/discussions/0/846958724834033563/

It's highly likely this will be the cheapest you'll be able to get the game (the dev even said so), so if you have any interest in the game, you should get it now. However, even if you buy it now, it may be best to wait for a few more updates to actually play it unless you just want to check it out.
