Doodle Arena

"Doodle Arena" is a casual browser-based battle game where you defend against waves of enemy doodles, leveling up by collecting orbs and utilizing power-ups like "Frenzy Mode" and "Invisible Mode." Enemies grow stronger and gain enhancements as you progress, and you can earn diamonds to unlock more powerful doodles and items. The goal is to survive as long as possible against the onslaught.
