Project Exilium - Breeding Protocol

Project Exilium – Breeding Protocol is a sci-fi, roguelike deck-builder inspired by Slay the Spire, where strategy and NSFW collides.
You command a party trapped in a hostile alien system where survival depends on mastering unstable elements, strange technology… and a Breeding Protocol that you activate by reaching maximum lust.
Every run is shaped by your choices:
-
The elements you select (each character combination gives you access to different cards and playstyles)
-
The cards you obtain
-
And how deeply you embrace the system’s lewd and dangerous mechanics

-
Lewd Slay the Spire–style combat
-
Dozens of NSFW cards with unique effects
-
Multiple elements and deck archetypes
-
High replayability with different party builds
-
Dark sci-fi atmosphere with erotic undertones
-
Ongoing development with new content planned

A middling deckbuilder that falls into a few common traps:
- HP persists between combats, but there are reusable cards that heal you, incentivising you to stall the combat to heal up after defeating all but one enemy.
- Arousal also persists between combat, adding another incentive to stall until you are at 49/50 so that the first card you play next combat gives you an Ultimate.
- At Rest sites, entering the Shop refreshes it, letting you fish for specific cards.
- Also in the Shop, some cards cost 9999 credits for no apparent reason.
- I like how your starting deck and rewards pool is based on the 3 characters you choose
As an erotic game, I don't think it's very good. The cards show the girls in various situations, but most of the erotic ones show them on the losing side whereas I stayed well ahead of the enemies. There's a disconnect between the story shown on cards/animations and how the mechanics play out.
Thanks for the feedback!
Also the version numbering is a bit strange.
This is v0.1 while breeding empire was at v.0.2.6 last year.
It's a separate game, set on the same universe. Breeding Empire v0.2.7 will come out soon too
Please explain the differences between this game and Exilium - Breeding Empire. It looks almost exactly the same.
They are games set on the same universe sharing the same characters, however they are totally different games. Exilium: Breeding Empire is a base management with a 2d turn based fighting game among several other mechanics.
This one is a rogue deck builder with a linear storyline.
