Flagship Digital Collection
Knife and Card
"A collection of innovative and advanced memory card games"
Knife and Card compiles Valliberum's unique tabletop card creations into a premium, interactive digital video game format. Featuring both solo challenges and competitive modes against the CPU or a local Player 2, these are far from your standard memory games.
Each game in the collection is highly stylized and mechanically diverse. Some are pure memory challenges, while others integrate RPG-like battle elements, allow integration of chess pieces, or involve elements of nature, geography, fantasy, map navigation, and probabilistic guessing.

Vision
A call for collaborators
I love creating card games but, unfortunately, I'm not a visual artist myself. For this reason, I use AI to create the artwork for my card games and, to be honest, I don't think I could create them the same way without it. However, nothing would give me more joy than to see prints of the games with real art created by real artists.
I'm currently working on a zero budget, but here's the plan: if you're an artist and you'd like to create the art for a set, I'll send you a copy of the game for free. If we release it together, I'll share the profits with you.
In the meantime, anyone can download the PDF files for free on itch.io. Physical versions have production costs, but I prioritize keeping the digital versions accessible to everyone.
