Slime Castle — Idle TD Game

This idle tower defense game is played in short, repeatable sessions, likely in portrait mode and playable one-handed. While the core gameplay loop is solo and can be mindlessly grinded, progression is heavily gated by pay-to-win mechanics and a slow pace, making it difficult for free-to-play players. It's best suited for players who enjoy long-term idle progression and don't mind a significant grind or potential spending.
