About this game

Hero Party Must Fall is a 2DCG fantasy about exactly that: the Hero is leading the charge against the Demon King, and you are an ally. You are also the Demon King's spy, sent to break the party from inside.

The game stacks netorare, corruption, MILF, female domination and monster-girl content across a long campaign. Lactation, lesbian and interracial scenes layer the run.

A dense, fantasy-flavoured cuckold game with one of the more inventive premises in the corruption-game corner of the niche.

Playtest 1 Like I've said before, this is a short plot update that sets-up all of the endings. After this update, I'll release the heroine endings as well as others. I'm not sure if it's possible to cram it all in one update, most likely two. I'll judge it as I start working on it. After the endings, I'll work on polishing the game as well as work on the new project. Also very important, I want to create some polls to see where you guys stand and what you hope to see in terms of updates for this project and future projects. I have a lot of ideas but I want to know what you guys would like to see as well. How to unlock new scene? It's simple, it should trigger at the end of the last princess scene so exactly where the previous update ended. If you have a save just load it.
v0.5.8
Playtest 1 N/A
v0.5.6
Playtest 2 Load a save preferably from the start of arc3 (throne scene with Mars). If you can't, I guess you can trigger Erin's scenes with this console command (shift+o): random_ev_bag.append("h_f_paizuri_0") Skip time to trigger afterwards. For Elena, just click on her. What's added: 4 new scenes for genderbent Erin (1 animation) 2 new scenes for Elena (mostly plot, not H) 2 little minigames like the governing one I was gonna add a scene for femdon erin, I have the CGs and everything but writing the scene would have taken some more time. I also did an H animation with Elena but ended up hating it so I scrapped it lol The minigames in this arc have to do with how Mars runs the town. They affect Mars' approval, a good approval value is needed to get the good ending. The first minigame added is supposed to mostly waste Mars' time if interacted with, but occasionally some important tasks are presented to Mars that are worth interacting with. The second minigame is the opposite, they are for events that affect the entire town. Other then approval, they also deplete his Hero's power. So the idea is one minigame for governing/justice, one for managing petty problems and one for managing disasters. It's gonna take some time to shape, but hopefully bit by bit the message can get across.
v0.5.6
Playtest Hello everyone! Very happy to share with you another update! This one was very tricky, focusing on many characters at once and as usual it's a race to cram as many events as possible. This is one of the wordier updates. There is a lot of yapping in this one But it's necessary to give context to H scenes... In the end, I barely found the time to lay out all the mandatory events, but couldn't finish up a gameplay system that was planned to be used with "Governing" to trigger events. So in this update, the events will trigger after skipping time. This is temporary, I'll add the system in the future. Content and how to unlock: Queen events: Use govern command in the morning, choose "Forced lxxx" when it appears Princess events: should trigger on their own Elena's sister events: should trigger on their own Revenge Erin: They only trigger if you pick Elena's ending in the last arc and only after you do govern command for the first time There is a unique fem erin scene that triggers if you picked that There is a unique ceci event that only triggers if you picked her ending last arc For all of these events to trigger, you need to load a save from the start of arc3. During the introductory scene of the town. If you don't have it, you can use this console command (shift+o) to load up the triggers: renpy.jump("last_arc_tr") Other useful commands: Female erin: erin_f = True Change last ending to Elena: arc2_path = "v" Change last ending to Ceci: arc2_path = "p" Force load revenge erin events: random_ev_bag.append("h_revenge_0") Future plan The plan hasn't changed, the main story of arc3 will be split on 2 updates, this update is the first part, you can think of it as build up, second update will finish up the story. That will leave the endings for the game which I'll do in a seperate update. After endings, I plan to do additions and improvements on a monthly basis until hopefully the game is less crap That is all, any feedback I'm always here! As always, thank you so much for your support! I appreciate you for sticking with me!

Developer Notes
This game is centered around Netori. The protagonist will be romantically involved with a heroine already in a relationship.

Later it will be possible to have Erin be feminized and turned into a potential heroine. Or ignored altogether.

Q: What's Paths?

A: In-game skipping functionality. Because saves break for certain updates. You can use that functionality to jump to the start of any previous update.

Q: What's Memories?

A: Gallery.

Q: What are specks?

A: Hero power turned corrupted when a heroine engages with Mars. In-game currency for Helelle's shop.

Q: Can't access gallery. Something about not waking up.

A: Start a new game and finish the prologue. Then save anywhere. You'll be able to access memories now.

Q: What's an 'NPC'?

A: All non-main characters scattered around the village. All their content is optional.

Q: I'm stuck training Cecille for the second time. Story won't progress!

A: You need to do the Lavinia events in the afternoon. Reading book and going on dates with her.

Q: I don't see any commands besides Talk for Lavinia

A: Open up console and use the following command:

can_read_book = True

Q: I'm still stuck after the dates!

A: If you haven't seen Erin's peeking scenes and already played through the garden mini-game at least once, use this command on the console:

sum_event_bag_prio.append("p_sum_1_sp_2")

Then train at night with Cecille to progress the story.

Q: Game is unresponsive on JoiPlay !

A: You need to set "Use legacy version" on. This setting was removed on the latest JoiPlay version. So you might need to use an older version like 1.01.400.
