Deep Delve is an arcade timing game where you control a spelunker exploring a crystal cave.
Tap the STRIKE button at the right moment to hit crystal veins and descend deeper. Accurate hits give crystals, while missed hits reduce your available torches.
As you go deeper, the marker moves faster and the target area becomes smaller. Collect crystals, build combos, and try to beat your highest depth record.
Spend collected crystals on permanent upgrades that improve gameplay, including easier targets, more torches, and slower movement.
The app includes a menu, gameplay screen, upgrades store, instructions, and settings.
Progress, records, and upgrades are saved locally on the device. The game works without registration or an internet connection.
