The game has intriguing idea an is set in an archipelago you instantly want to explore. Contains some funy descriptions of fish warped by Dagon(?). The game would have benefited greatly if the dialogues were presented in a more immersive way. Sadly, after an hour or so, you realize that there are but two game mechanics - fishing (presented in three ways + dredging, but really the same one click mechanic) and halluzinations at night - and you have to finish all tasks in one predefined way. Replayability therefore is not high. Buy in a sale, if you want to enjoy one or two evenings of fishing, mild lovecraft references and reading.
The game can be completed within 90 minutes. No quest that I found had more than one way to finish it - you alway click through several dialogue screens, get items on several different portions of the map (tedious, without this "feature" the game would be 30 minutes long) and use them to get another dialogue. Neither can you influence the outcome nor do you have any decision to make throughout the whole game. Every task ist completed in the same way.
