Gameplay and Story Premise

Castlebound follows the journey of Lenora, a skilled archer, and her grandfather Vargus. The pair awakens an ancient, sentient structure that transforms into a "walking castle." Guided by a mysterious character named Coronya, players must gather a party of warriors to defend this living fortress against waves of monsters.

Key Features

• Defend the Walking Castle: Unlike traditional tower defense games, the objective moves through various dangerous environments, requiring players to protect the structure while it is in transit.
• Solo or Co-Op Action: The game supports 1-4 players. While solo play is fully supported, the game emphasizes local co-op. Note that additional controllers are required for local multiplayer sessions.
• Roguelike Elements: Each run is randomized. Players can unlock new skills, heroes, and permanent upgrades to increase their survival chances in future attempts.
• Multiple Heroes: Beyond Lenora and Vargus, players can unlock different warriors, each possessing unique abilities and playstyles.
• Combat Mechanics: The gameplay focuses on fast-paced 2D platforming combat, including jumping, dodging, and unleashing specialized attacks.
