This game’s pretty rad

Full disclosure: No connection to any developers or reviewers, and I think that super negative review is harsh and unfair. My 4.5 year old kid, who can read, totally digs this game after two weeks of playing it. It’s beautiful, it’s filled with all the Octonauts, and so many of the creature characters that appear in the cartoons. He says stuff like “Hey, that’s Parrotfish Pete” as he toodles around in the Gup going down into the midnight zone to see the vampire squid.

I don’t buy games, but I bought this one despite the negative reviews, and I’m so glad I did. Keep it up devs! If you add an Octopod addition to this game like some other reviewer mentioned, I’d gladly pay for it.

To the Launch Bay!


Beautiful graphics but light on content

Though I was initially impressed by the high quality graphics, I quickly became disappointed with the lack of educational content. I was expecting more from this franchise after the standard set by the show and books. This could be solved by adding in the “creature reports” to the creature cards (“Elmo’s alphabet” app is a good example of this) or replicating some of the problem solving from the show. The bones of a great app are here, it just needs to be fleshed out.

I would also like to see the ability to go inside the Octopod, if only to satisfy my own curiosity it’s potentially non-Euclidean nature.


This could be a 5 star game, but there is no content

DO NOT BUY THIS GAME! The developer will contact you and try to get you to change your review unless you give them the one they want BUT DO NOT DESERVE!!! The content in this game is NOT WORTH BUYING, especially not when it comes with harassment. DO NOT PURCHASE THIS GAME!

Original review:

This game blew its budget on making it look gorgeous and forgot to pay a cent for content. It's not worth the cost AT ALL. At least make the different ships have different kinds of missions. But honestly, please add way more types of missions, and more game-play content overall, there are only three and each mission of those are basically the same (drag object to other object). So much disappointment!

Developer Response

We love that you think the game is gorgeous—thank you. We're sorry to hear that you didn't find enough missions—although there are many more than three, including photo hunts, creature collections, and other hidden mysteries. In any case, we love the challenge to keep adding more, so thank you again for your comments. For what it's worth, one-star reviews can take the wind out of a developer's sales and hurt overall sales, to the extent that future revisions end up being out of reach; a few more stars help keep the whole adventure unfolding!
