Sealing Tower

This is a deck-building rogue-like game inspired by Slay the Spire. The player takes on the role of a Taoist who accidentally enters a forbidden place—Sealing Tower—and becomes possessed by the spirit of a demonic sword, thus trapped inside. To escape, the player must defeat the monsters within the tower, acquiring new cards to build a unique deck along the way.
Building on the foundations of traditional card-based rogue-likes, I have redesigned core systems including the card distribution mechanism, map structure, and progression system. Players will need to adopt entirely new deck-building strategies, offering them a fresh gameplay experience.
To ultimately escape the Sealing Tower, players must navigate through a series of maze-like maps. Along this journey, they will not only engage in battles but also encounter randomized events involving neutral creatures, gradually piecing together the backstory through fragmented narrative elements.
Yin-Yang Mechanic
The game introduces Yin and Yang, a traditional Chinese philosophical concept, as one of its core gameplay systems.
Specifically, players have a Yin-Yang bar (as shown in the diagram) that indicates their current Yin-Yang value and status.

When players use cards or take damage from enemies, they gain corresponding Yin or Yang values. Once the ratio reaches 70:30, players enter either the "Silence" (Yin-dominant) or "Violence" (Yang-dominant) state, receiving bonus healing and increased damage.

However, players must be cautious not to let their Yin-Yang values become too imbalanced—doing so results in instant death. This mechanic reflects the Daoist principle of maintaining harmony between Yin and Yang.
Yin and Yang also influence damage types, with interactions like minor effects or counters.
