Learn About the Game Castaway Island TD

Castaway Island TD drops you on a remote land swarming with monsters. You play a lone hero planting defense towers along winding paths. Each tower fires at incoming foes and keeps them away from precious crystals.

You pick one companion at the start. That pet fires special attacks or grants passive boosts. Each ally grows stronger alongside your towers. Bright gemstones dot the island and power up every defense. Every level brings new terrain and fresh dangers.

Success here depends on smart placement and timely upgrades. You study enemy patterns and shift your defenses mid-battle. The vibrant colors and subtle tunes set a relaxed mood. Pushing back each monster wave feels rewarding.
