[Mod] KayceePvP, real 2-player online PvP for Kaycee's Mod, Beta looking for testers

Part 1

I built a mod that turns Kaycee's Mod into a real 2-player PvP experience, instead of the usual solo run against the AI.

How a match works: both players prepare their own deck on a shared map (same layout, same seed), drafting and trading cards, fighting the map's own encounters, picking a rare reward, and on some maps even creating a Death Card. Once both decks are ready, the two players duel head-to-head over a real network connection: a shared damage scale tips toward whichever side is winning, life runs on a two-candle system, and matches are best-of-three with rematches that don't require restarting the whole run.

Six preparation maps to pick from:

  • Something close to a normal Kaycee's Mod run: battles, drafts, a boss, a Death Card
  • The same shape with zero combat
  • A linear route with two non-final bosses
  • A pure pelt-trading draft with no combat at all
  • A tribe-focused draft
  • A route built from a large simulated search specifically for balance between two mirrored players

Getting into a match got easier this update: a host can mark their room public, and the other player finds it directly through Find Match, no invite code to copy and paste. A private invite-code room and LAN play (same local network) both still work exactly as before.

It's in public Beta right now. The core loop (lobby, map prep, the duel itself, best-of-three, rematches) has been tested and works. What it needs most right now is more players hitting more card/sigil combinations than two people can realistically find alone. Some specific interactions probably still aren't perfectly balanced, and a few might not sync correctly between the two players yet. That's exactly what this Beta is for: the more people play it and report what looks off, the faster it gets genuinely fun and solid instead of just "working."

Install: search "KayceePvP" in the Thunderstore Mod Manager or r2modman (Inscryption game), choose "Install with dependencies". Both players need the same version.

Feedback: press F10 in-game for a short form where you can report a bug, share a suggestion, or ask a question.

Known limitations are listed on the Thunderstore page, nothing there should stop you from playing a full match, just things I'm aware of and still working on.

Would love for people to try a match (or several) and tell me what breaks, what feels unfair, or what's just plain fun. Thanks!
