Drilla: Idle Digging Game

This is a portrait-oriented idle clicker game that can be played one-handed for short sessions, making it highly interruptible and suitable for quick check-ins. While it offers high replay value and a mindless progression loop, its monetization heavily relies on ads and pay-to-progress mechanics, and it requires an internet connection to play. It's best suited for players who enjoy passive progression and don't mind frequent monetization prompts.
