Jellyfish blind box 水母盲盒 is an idle game that looks like an aquarium filled with jellyfish. As the jellyfish grow, you can sell them for more than you paid for them, allowing you to get newer, higher-quality jellyfish to make even more money.
Cute Jellyfish With Nice Noises
I’ve had Jellyfish blind box 水母盲盒 running in the background while I do just about everything for the last week and a half. There is something so calming and lovely about having the aquarium noises running while I work. Jellyfish blind box 水母盲盒 is the kind of idle game that is unobtrusive, beautiful, and comforting.
There are tons of fish you can get, and all of them have unique little bodies, decorations, and looks. They start simple like this little jellyfish here:
To jellyfish with crowns and castles on their heads, like these:
The more you spend on the fish, the more elaborate they get, and the more adorable they get as well. There are a boatload of different kinds of fish you can collect, grow, sell, and use the proceeds to buy more. Most of the time, you can let it idle, just sitting in the background and growing your fish. Or you can proactively feed your jellyfish with the right mouse button to make them grow faster.
With the money you earn, you can also purchase new backgrounds, new foregrounds, and additional space in your aquarium. For each additional space you buy, it upgrades your right-click feeding as well, making it so your jellyfish grow up faster when you are actively engaging with them.
There isn’t a whole lot to do in Jellyfish blind box 水母盲盒, but that is the point. It’s just a calming little game you run in the background that you can tinker with in spare moments or stare at when you get stressed.
The Cons of Jellyfish blind box 水母盲盒
Jellyfish blind box 水母盲盒 is a very simple game, which is good for an idle title. However, I think there are some things that could really improve this game.
- There is no bulk selling button: The main loop of the game is to buy jellyfish, grow them, then sell them. You can bulk sell if you have more than one kind of jellyfish, but a button that just lets you sell all grown jellyfish would be great.
- The sell menu closes when a jellyfish levels up: If you click on a grown jellyfish to open its sell menu, then another jellyfish levels up to its full-grown form, the sell menu just closes itself.
- More decoration choices that are cheaper: The only things you can change about the background are the looks and the way the foreground looks. The cheapest of these is 1000 money, and that takes a long time to get to. I wish the developers had added more options with a few of them cheap so you had more options to alter things early game.
- Upscaling: Jellyfish blind box 水母盲盒 looks great at 1280×720, but if you try to full-screen it any bigger than that, it looks pixelated. I wish there was a menu button for upscaling that made it look better.
- Instructions: This game tosses you in with no tutorial and no explanation for what all the symbols mean. There are little day and night icons in the jellyfish selling menu that I have no idea what they mean. I just kind of had to stumble through it at first until I figured out how to feed them and how to sell them, etc.
Conclusion
Jellyfish blind box 水母盲盒 is cute, comforting, calming, and a great addition to my desktop that is probably going to live there for a long time. It’s colorful and the fish are adorable; I like it a lot.
However, there are a handful of things that I think could be improved. Overall though, I like it, and I hope we get more updates for this relaxing little idle game.
Final Verdict: I Like it.
