Pros:
Actually I really prefer the progress to be keep on this speed. In my opinion it's not too slow. I actually prefer that way. I can collect items for a long time, and it doesn't matter as long as I have an aquarium by my side and I can travel around the place in the new mode, unlike previous updates. Why, I prefer not too fast?
Because in my previous experience with types of games like this. If the progress is fast you might will find the game "dead", and by "dead" I mean.., almost....almost there is no something new to unlock. You wanted to move on and discover a new place or something new but with the game's gameplay system, the progress is too fast, causing you evolving in no time. The boss is too easy, but it should be keep in hard level, and so with the materials, it should be keep a bit difficult to find them, so the game won't reach it's end soon, and you will be bored. I know not all players agree with this, especially a slow progress game is not their type, but since...this game is still new, a fishing theme and ofc unlike other big games, there isn't much for people who doesn't like waiting to catch fishes. I, personally, aside from my passion to fishes, and sea animals, the reason why this game was still hanged in my head, is the iconic graphic and unique game play of the game. The new fishing mode, where we can go on a camera with a front angle is the most update that had huge impact on me, now we can feel like we're on travelling while go catching some fishes :D, which without it I may won't came back to play it again. Unlike many other fishing game, this one is actually the closest one to my top list.
