Clockwork Aquario is something of a unearthed treasure in the video game world. Originally created in 1992 as an arcade title by the now-defunct Westone (creators of the Wonder Boy series) and to be published by Sega, Clockwork Aquario ultimately went unreleased. In 2017, Strictly Limited Games acquired the rights to the game from Sega. But some of the game’s code had been lost over time, so Strictly Limited Games teamed up with ININ Games to help fill in the gaps. After a few more delays, Clockwork Aquario FINALLY saw release on Nintendo Switch and Playstation 4 at the tail end of 2021, nearly thirty years after the game was originally created (claiming the record for longest development time in video game history in the process).
On the plus side, it’s nice to know that such a game has actually been released after seemingly being lost to time. On the down side, the story behind Clockwork Aquario is more interesting than the game itself. Clockwork Aquario provides some fun, arcade-style platforming, but it’s short lived and lacks substance. It’s an entertaining novelty, if maybe not the arcade classic you may have hoped for, given its unique development history.
Clockwork Aquario is an action-platformer in which players can choose from three different playable characters: a boy named Huck Rondo, a girl named Elle Moon, and a robot named Gush. While all three characters have their own animations and sound bites, they all play identically. The goal of the game is simply to make it to the end of each level, defeat the boss, and ultimately defeat the evil Dr. Hangyo (an anthropomorphic fish, of all things) from taking over the world.

The stages are short and straightforward. There’s a time limit on each stage, but I’ve not had it run out on me yet. Each character can either jump on an enemy or slap them, with one hit stunning the enemy, and the second hit defeating them. What’s fun and different about Clockwork Aquario is that once an enemy is stunned, you can lift them up over your head and throw them at other enemies. It’s reminiscent of Super Mario Bros. 2 or Treasure titles like Mischief Makers or Dynamite Headdy in that respect. Also similar to Treasure titles are the big, ridiculous boss fights, all of which involve Dr. Hangyo piloting a crazy, animal-shaped robot.
Although the core gameplay is fun, there are some annoying aspects to it. Namely, there are numerous segments where enemies pop out of nowhere as soon as you’re on top of them, to the extent that it feels like you have to take a hit to move on. That would be an issue even if you had a health bar, but it’s all the worse since your character can only take two hits before you lose a life. Another issue is that it takes way too long to gain a single extra life. By defeating enemies and getting points, as well as picking up gems the enemies occasionally drop, you slowly build up a meter towards collecting a 1-up. But you’ll often lose all your lives and an extra continue before you fill the bar up, so it feels like the reward isn’t worth it. It’s also annoying that you can’t pause the game once you start. I get that this was originally made as an arcade title, but come on. It ended up released on home consoles. Surely they could have added the ability to pause.
You’ll also find that the game is incredibly short, even by arcade standards. Clockwork Aquario contains only five levels, each of which can be breezed through long before the clock runs out. The game features different difficulty settings, but the only real difference is that the harder difficulties give you less continues (seeing as this is an arcade game released on home consoles, you can’t keep giving the game quarters for more chances). There’s also a ‘training mode’ but that’s little more than playing the first two levels with unlimited tries (which is really weird now that I type it out). You’ll also probably feel that, unless you have a second player with you, there’s not a whole lot of replay value here.
If there are two areas where Clockwork Aquario shines, it’s in the visuals and music. The graphics, character animations and backgrounds have a fun, retro anime vibe. It all looks so smooth and colorful! Clockwork Aquario looks like a suped-up Sega Genesis title. The music is similarly enjoyable. So much so that the game even includes its soundtrack in the main menu (both as the tracks appear in game as well as remixes). Clockwork Aquario is very fun to look at and listen to. Unfortunately these aesthetic pleasures don’t translate to the menus, which are pretty basic and mostly just text.
Clockwork Aquario is decently fun while it lasts, but I do think you need two players to get the best out of it (there’s even an extra mini-game in between the third and fourth stages only when playing with two people). Given the game’s unique history, you do kind of wish there were more to it. But it’s still a fun, novel experience. And worth checking out as an odd little piece of gaming history.
