The Devourer is always hungry and it’s your job to feed it in this idle merge game mashup. Play as the NecroMerger and use dark magic to summon an army of creatures (skeletons, zombies, demons, banshees… the list goes on). Merge them from piddly little grunts into massive (and tasty) brutes, before feeding them to your ever hungry pet.As you grow your Devourer you’ll attract the attention of merchants, champions and even rivals. Some can be useful, others must be fought… or fed to your insatiable pet. The bigger the Devourer grows the more your lair will expand and you’ll unlock powerful abilities and spells.
Complete feats to unlock new stations and equipment… graves, altars, fridges and even a bathtub to hold excess slime. New stations will let you summon new, stronger (and even more tasty) creatures. Manage your lair and minions to maximize your resource generation.
NecroMerger is a whole new type of game that combines merge and idle mechanics with resource management to create something truly unique.

Pull rabbits out of hats, grow giant beanstalks and grant wishes all to impress the SpringSpector. There are rewards for hard work, three skins, a new theme and loads of relics await those who can pass the test.
+ To start the SpringSpection event you must have a lvl 21 Devourer (or have prestiged) and unlocked and visited the Vault.

I absolutely love this game. Have gotten pretty far, and even put money in, but I am about to uninstall because the game keeps freezing up and crashing my phone. I have to restart the whole thing. At first I thought it was my phone, but my husband has a much better phone and downloaded to play too, and it did the same to his phone. It gets annoying having to restart my phone 6 or 7 times just to play.

Nice casual game. The ads are too much though. I know you don't "have to" watch them, but you kind of do or else you can only play 1/4 as much and will miss all of the timed events. The quick ads are pretty reasonable. The minute+ ads that make you wait to tap 3 different X's and still take over your phone to open the app store are overkill.

I like the little nods to the other game, like the Necromerger's comment about his robes. The energy refill feels a bit slow, but the idle offline makes up for it, as well as the chance to use the ad watch to refill either energy or slime. In recent updates, however, the ad watches have failed to let me unlock the chest.

I love this game! You can tell it was crafted with love and time instead of the capitalist slop that is most of the app store. Gameplay is exactly like the ads, and it's super fun. It's unfortunately not something you can play for hours straight (or I definitely would), it's more a game to check in on every few hours. I've been playing for days and only got one ad, and it was for a reward and non intrusive. You don't need to pay to progress.

I think a great quality of life addition would be for the crashed saucer to have a meter bar/count down per tap. Upon depletion, the color will change (maybe indicate what the color is next). I cannot fathom how many times I've had this scenario happen where two resources are completely full; start to merge aliens for cosmic runes mid way my mana switches to slime that I'm out of, stopping the flow of the game. This would allow the player to strategize ahead of time.

really pleasing, strong artistic direction throughout the dev's published games. ads are easy to avoid, well incentivized with rewards, and will never forcefully play. paid currency (gems) are rewarded often enough that you never feel pressured to buy to have a good experience with the game. really great longetivity as well. keep an eye on this dev!

this game is one of very few idle-merger games that I can stand to play and it is absolutely one of my staples in the mobile game genre. it hits all of the genre specifics on the head and does them very well. the idle aspects of the game is a little weird to figure out at first but once you get the hang of it, it's very forgiving and you can speed things along based on your personal efficiency. overall, I'd recommend this game to anyone who just wants to kill some time in a slightly funny way

I can't seem to put it down. 10/10 Pixel Graphics, Music, and Story. I can't wait to get my little beast to eat the world. It maybe slow at first but if you give it time and learn space management. This game gets Better. Love the new update. Even more monsters to collect. I hope to see how it ends or will it go on forever. Either way I will never stop playing. Keep up the good work Devs!
