Comments on KATOA: Oceans for Android

★★★★☆ tyson richards · Jun 6, 2023
Very enjoyable and well-made game, with a great message. I have thoroughly enjoyed playing this so far and will continue to do so. Waiting for multiple raids just to complete the daily quests on several different locations becomes tiring and time-consuming. There is significant lag during the blight attack mini-game when many objects are positioned in the frame. Besides, these two points, I love it!
★★★★☆ Cailin Brown · Jul 14, 2024
It's a pretty cool game, I like the concept and actually helping to pay in one way shape or form to help the ocean is nice. However, I've been playing for a long time, and I don't know how to unlock the next haven. I have the next mini haven, Shackleton ship or something I forgor, but after that everything is locked. Is there content that is going to be added? Do I need to do something specific to unlock the rest? Is this a bug? Help I want to build another haven.
★☆☆☆☆ Robin Woodard · Mar 7, 2024
I wasn't able to play long enough to give a good review, hence one star. Every time I try to enter my haven I get a "fetch haven failed" error (might have different wording). Otherwise... I like the utilization. The game isn't very engaging, but feels more like a game you check for a few minutes during a work/school break, which is fine. I don't get how playing a game helps organizations, I didn't see any info explaining it while I played; I would like to see that added, and to be able to play.
★☆☆☆☆ Peter von Feldt · Feb 20, 2024
Controls are non-existent. Tap and slide tactics are really not working with this game. Also let us customize the avatar and explain what every arrow does because what you have isn't explained. Playable, yes, however unless this is updated, I really won't be playing it.
★☆☆☆☆ Mike Cheadle · Sep 22, 2023
Love the concept and was enjoying the brief time I got to play the game, but it is buggy and fundamentally does not work. Now whenever I enter the Great Barrier Reef the haven loads, but I can't do anything no UI controls or interface loads and the only way out is to quit the game. I can go into and play Shackleton's Shipwreck and that works fine. Have contacted the Devs and had zero response so seem like they don't care either. Don't waste your time.
