Buy Now$6.99 USD or more


Mammon City can be a rough place to live. Devils are everywhere, and the only decent job in town is hunting them down. Take charge of Sophie, sword priestess and generally anxious mess, and Anna, fire witch and localized disaster, as they fight, flirt, and just try to pay the rent. Hunt horrifying devils, confront your corrupt employer, uncover the horrible secrets behind Mammon City, and prove that evil doesn't stand a chance against the power of girlfriends.


  • Lightning-fast, rhythmic boss fights in a unique dual-hero battle system - block, counterattack, and overwhelm enemies!
  • Build up combos for extra damage and stun your enemies with LOVE Breaker!
  • As long as either Sophie or Anna remain standing, she can revive her girlfriend!
  • Meet a colorful cast of queer miscreants!
  • Text your friends! Text your enemies!
  • Flirting! Dating! Lesbians!
  • Powerful chiptune soundtrack by RoccoW.
  • Gorgeous art by super-talented indie illustrators.
  • Granular difficulty options for those who want a relaxed experience.
  • An in-game wiki full of classified boss info.
  • Leaderboards (now your friends are the boss) (coming soon!)

Really good! Played on iOS, it was great for pick up and play sessions (“just one more boss…”) that often had me playing for longer than I intended. Really fun combat once you get the hang of it, with extra performance incentives for replays. Lots of love in this game and it shows!

Ahh, I'm so glad you enjoyed it!! I had fun trying to design a combat system that felt fun & easy to understand, with lots of small hidden depths. Thank you for your kind words!


Thanks for the excellent game! I was part of the booth next to you at Youmacon so I was happy to see your game featured on Itch! Good job!

Ahhh, hi there!! Thank you so much, I'm glad you liked it ✨ it was great having you all as boothmates!


I just finished this game :) I was really invested in it both for the story and the fights :D Thanks a lot for making it <3

If you (or anyone reading) have recommendations for other great android games, I'll happily take them :)

Thanks so much for playing, I'm really glad you had a great time!!

And yea, I'm happy to recommend some! Some of my favorites the past few years have been:

  • Gun Rounds (action arcade game about a gunslinger, great for playing just a few minutes)
  • Magic Survival (strangely forlorn action game, it was the inspiration for Vampire Survivors!)
  • Golf on Mars (relaxing and stress-free golf minigame)
  • Reigns: Her Majesty (guide a kingdom to wealth or ruin with your decisions, die a lot, try again - funny writing)
  • Slice & Dice (one of the single best roguelike dungeon crawls I've played)
  • Isle of Arrows (a simple but satisfying arcade Tower Defense game)
  • Mystic Messenger (dating sim /  visual novel detective mystery that takes place in real time)

I wrote up a post about some faves a while back, if you want some more details: https://lilycore.neocities.org/posts/2022-06-07-Hidden-Gems-Of-Mobile

Unfortunately, I don't know many other mobile games with a strong focus on  story; if people know of any I'd love to hear about them too!


Thanks a lot for the recs :) I bought Golf on Mars and Slide & Dice based on your suggestions, and I'm SO invested in the latter! I recommended it to several friends who I know are into this kind of games :) I'll look into the others as well (especially interested in Mystic Messenger).


Love this game. Terrific story and humour. Also has lots of mileage for speedrunning. Favourite character's got to be Omeghost. Can't wait to see what comes next 😍


Thank you so much for playing, I'm glad you enjoyed it! Omeghost is one of my favorites too 💜 And yes, I love watching speedruns, and tried to keep speedrunning in mind while designing. There's already been some cool boss rush speedruns that have been a blast to watch!


I 300% ADORE this game. Probably my favorite queer writing style since VA11 Hall-a, and everything comes together so nicely, great music, simple yet complex gameplay, gahhh this is so good I stg

can we get a community discord going? I'd love to discuss this game and similar ones/other games from this dev with likeminded people


Ahhhhh, thank you so much, I'm so glad you enjoyed it!!

I have been thinking about starting a community discord server at some point, but there isn't one yet - so thank you for letting me know you're interested! If I start an official one I will make an announcement update here :)

I finished this game on stream yesterday, and I absolutely adored it. 💖 The writing hit really close to home sometimes, but in a way that I appreciated and that made me feel seen and understood.

Also, the finale shows that this is the kind of game that a corporation simply could not make, and I adore it all the more for that. :3

This really made me smile!! Thank you so much again for streaming the game <3 I'm so happy you enjoyed it!


Juste finish the game and i am glad i give it a try . Great gameplay ,a touching story. Seriously one of the best mobile game i never play.  Thanks for this game :) 

I am so glad to hear that you enjoyed it :D thank you so much for playing!


bought it today and im so in love!

however i just wanted to point out a possible issue.

it looks like the game screen is slightly larger than the actual screen on my phone, make it a bit difficult to press the button on the right hand side.

have you received other reports? or am i the only one so far?


Shoot! No, I haven't received any reports like that so far, but I'll look into it. If you don't mind, would you let me know what model phone you have? A screenshot would be helpful, too - either here, or via email at lily@lilycoregames.com. Thank you so much!


Okay this is my favorite game of this year, and probably the two years on either side of this one


Ahhhh, that means the world to me, I'm so glad you enjoyed it! Thank you so much!

I really like this game.

Thank you so much, I'm glad!

Reminds me undertale.

I definitely got some art inspiration from Undertale, but it's a bit more fast-paced :D


If the final boss isn't actually My Heart, I'm not playing.


Is it your heart, or my heart? I won't spoil anything :)


Me after reading the description "Shut up and take my money"

Ahahaha, I'm glad I hit the mark!!


I don't know what's funnier the implication that hunting demons are the only/primary way of making ends meet or that they continue living a place called "Mammon City" 


Hahaha, times are tough... Like, really tough :P


fantastic play, left a review on the playstore!! it's just fun and engaging and the music is right up my alley.

thanks a bunch for options that make the game easier!


Thank you so much, I'm glad you enjoyed it!! And I'm glad the options were helpful :)


This game has been amazing so far. Feels like light-hearted anime meets Elden Ring. Highly recommend!


Ahhhh, I kind of love that description :D Thank you for playing!!


Love the game, more people need to hear about this! I'm completely stuck on a certain boss fight where a death timer is introduced in the final phase. It seems to just be mathematically impossible to win... anyone else gotten this far?


Thank you so much, I'm really glad you're enjoying it!! Good luck, I hope you beat the boss soon <3


I heard you on TTWAV, I’m hyped for this game!


Ahh, yay :D Thank you so much, I had a lot of fun on the show!


Very excited!


Thank you <3


YESSS!!!! So excited for this game! <3


Ahhh, thank you so much! <3 <3


You're very welcome :D
