Some new features have been introduced (I will elaborate more on the unfortunate changes to the bonus system in 'The Bad'). Unfortunately, the amount of points received is quite small and, as before, the game progresses very slowly after the first few experience levels. Since most achievements are won in match-3 gameplay, not in aquarium area, an icon indicating a new achievement appears and the player can pick up prize for this achievement. Now also each completed level gives not only virtual money, but also some experience points, both money and points are also given for each achievement. In 'Depths of Time' the abovementioned lacks were corrected. Achievements are a popular idea in games since the advent of platforms such as Steam, but not always are they really integrated with the rest of the game and in 'Fishdom 3' they weren't. Achievements weren't integrated with gameplay - they were just an extra feature, just for satisfaction.

Experience points were only given for purchases, their results such as winning a cup, and for feeding fish and cleaning tanks.

In 'Fishdom 3' the system of experience points wasn't fully developed yet. Making this comparison is also useful insofar that it allows noticing a few improvements. It's closest to 'Fishdom 3': the same graphical style, the same gameplay mechanic with no level score, a simplified system of cups for well-developed aquariums and experience points. 'Fishdom: Depths of Time' could actually be called 'Fishdom 4' because it's clearly the latest part of the basic series.
