About This Demo

Experience a roguelite deckbuilder without energy or action points: there's no limit to how many cards you can play, as long as they fit! Every card is a sigil you place on a grid, each with its unique shape, keywords, and effects - turning each combat into a tactical optimization challenge.

Create powerful synergies through rune positioning, adjacency, overlap, and persistent effects. Place the right sigil at the right time to trigger devastating combos. Beyond spatial strategy, Moonsigil Atlas is about creative deckbuilding: draw infinite cards to deal infinite damage or make ten copies of your strongest card.

A fully modular, player-driven upgrade system. Every card can be modified as you see fit: reshape them, inscribe runes, add keywords, and more. Spread power across your deck or invest everything into a handful of unstoppable cards. With tens of thousands of possible combinations, even the simplest cards can become build-defining centerpieces.

With 250+ cards, alternate starting decks, unlockables, forbidden cards, 3 characters with radically different playstyles and a fully randomized map, every run offers new, game-breaking possibilities.

Battle dozens of astral entities and three Titans that reshape the board itself. Hostile zones, shifting grids, and unique win conditions turn every encounter into a test of adaptation and mastery. A powerful deck is only half the battle…
