Moonsigil Atlas is a roguelite deckbuilder from Snake Tower Games that forgoes traditional energy systems: you can play as many cards as you want, as long as they fit on your grid. Each card represents a seal of a unique shape that you place strategically gameplay focuses on spatial placement, adjacency bonuses, stacking effects, and creating powerful combos through clever card placement. A modular upgrade system lets you reshape cards, apply runes, and add keywords to customize your deck, whether that means evenly distributing upgrades or creating multiple, overpowered centerpieces.
