Editorial Meh

Project Exilium: Breeding Protocol is a Slay the Spire–inspired deck builder with a pregnancy fetish theme. The card-game foundation is genuinely solid — players who engage with the mechanics find it engaging and well-paced for the genre — but the execution is marred by significant technical problems: crashes on certain animations, array index errors mid-battle, disappearing cards between rounds, and exploitable balance bugs that break difficulty. The game also suffers from poor UI clarity (card effects unexplained, unclear who is speaking in dialogue, Patreon gating not signposted), and the sexual content, while present in card art, feels disconnected from story or mechanics. Community sentiment is divided between those who see promise in the core game design and those wary of the developer's pattern of frequent rereleases and abandoning prior projects without completion.

Description

Project Exilium – Breeding Protocol is a sci-fi roguelike deck-builder inspired by Slay the Spire, blending strategic card gameplay with adult content. You command a party of characters trapped in a hostile alien system, where survival depends on mastering unstable elements, strange technology, and activating a Breeding Protocol by reaching maximum lust during combat. Each run is shaped by your choice of party composition—different character combinations unlock unique cards and playstyles—as well as the cards you acquire and how deeply you engage with the game's lewd mechanics. The game features a 4-act campaign with unique bosses, dynamic dungeon generation with branching paths, and an Ascension mode with increasing difficulty tiers for replayability.
