Fantasy Idle Dungeon tasks you with capturing and evolving creatures called Jenin, then sending them into automated dungeon raids to grind resources and upgrades. The core loop revolves around setting up teams, configuring automation to run indefinitely, and managing progression through fusion and skill awakening. Best suited for players comfortable with extended idle sessions and willing to accept uneven pacing and sparse in-game documentation.

About this game

What players are saying

▼ Not recommended 4 hrs
The progression of this game feels off and the rewards for completing stages is not rewarding. Feels like the game is balanced around leaving it run on auto for 24 hours. It shouldn't be faster to grind gold for Jenins on stage 1-1 than at stage 7-5. Might revisit this game again in a few months if they rebalance the progression, but for now it's a no from me.

I have played 135 hours, and I barely understand what is happening in the game. There is a lot of it that remains untranslated, so I cannot understand some things. Each section should have detailed help, but instead, it's random whether help is available, and when it is, it directs me to a website that is in Japanese. I speak and read English. There should be detailed help within the game, in each section. Add a help button to anything that might be confusing for people, to make it easier to understand.

Everything in the shop is insanely overpriced. You mostly use the draw system because buying individual items is just a huge waste of money.

The forge lacks sorting and filtering controls. It needs more refinement.

The spirituality function in the Jenin Lodge is god awful. Very random, even when I have a Jenin fully evolved, trying to get exactly 50 is stupid and a waste of resources. It feels like I'm in a casino. It should require "over" 50, not exactly 50. That way when you get the 50 if you have extra you don't need to reset it, which is incredibly expensive to do. When I finally had the chance to use the system, it made me want to quit playing just based on the stupidity of the spirituality system.

Formations feel like they don't matter at all. And the ones that are chosen do not match what you would want to use. What is the point of having a tank class if there is no taunt, if a Jenin can just ignore the tank and hit anyone directly? Allow people to create their own formations, with the skills matching what they want in the slot of that formation.

Jenin Merchant should have some chance to get Legendary, but I have used it thousands of times and its never happened, so I'm guessing you cannot get one out of there.

The Idol system feels too random to be useful. And being told you need to unequip a Jenin because it has too many skills also feels like a bad choice. If you are trying to create a specific type of legendary you have to burn that Jenin and start over again if your Jenin has too many skills.

It feels like the game needs real polishing, but it has potential.

Despite all the things that I dislike about the game, it is fun to check the progress. But I've decided that I need to give this game like 6 months to see if they can improve it, and make it feel like a more polished, finished game, because right now its a mess.

If you want to get it on sale and try it out, it is fun. But the longer you play the less fun it is, because of all the problems you will find in the game. I cannot recommend the game at present but I believe in time we will see a decent game.

This game is really dependent on what you want from an idler game. As the name suggests, you capture creatures known as Jenin and send them off to raid dungeons. A cool thing is that you can set an automater to continue the same dungeon over and over infinitely until you stop it or to continue with the next dungeon once you beat the current one (not the recommended approach).

Progression is long, which for me is something I like as I typically want my idler games to be just that, idle, in the background on my third monitor, doing it's thing while I work, having something to look at periodically and then go in, spend resources to level up Jenin, craft items, etc. So if you're after a more fast pace idler where you have to do work, well go look elsewhere, this is not the game for you.

While the progression is very long, I tend to like it for my style of gaming. Jenin come in all rarity types from Common, Uncommon, Rare and Epic (from what I can tell so far). Don't be so quick to use your Epic ones though as often they can be weaker than your Uncommon's or Rare's. In fact, only 1 of the 6 Jenin in my party is Epic (Purple), all the others are Uncommon's (Green) and do double to triple the damage.

The first six areas are pretty straight forward and really only need Physical Attack Jenin priority, later on you do start reaching areas (levels) that require a variety of others so you will have to grind materials to level up other jenin so don't be too quick to get rid of them.

Overall I enjoy this game. While I feel the pacing could be a bit better, for my gaming style, it's ok. Not great, just ok. It's a fun little game but like all, after you get to a point, it will be repetitive and grindy so go into it knowing that and accept that as that's what these games all are, grindy, time consuming games.

Last of all, just enjoy the experience and have fun!
