Castella

About

Castella throws waves of monsters at your castle. Your job is to erect walls, place towers, and upgrade defenses to hold them back. Each playthrough is a test of strategy as you manage resources, choose building upgrades, and adjust to new threats. The fortress is your only line of defense against relentless enemies determined to destroy your base. Placement matters as much as firepower in this grid-based battle. What sets Castella apart is its rogue-like twist on tower defense. Procedural maps and permadeath mean every failed attempt reshapes your approach. With over 30 tower types and countless upgrade paths, the game challenges you to adapt quickly. Casual players find value in the straightforward mechanics while experienced tacticians appreciate the depth in placement and timing. The minimalist art style keeps focus on the tactical action without overwhelming new players.
