OneThumbTower

One-Thumb Tower is a tower defense you can actually play with one hand - in bed, on the train, or while holding a sleeping kid.

Every control is built for a single thumb. Drag a tower from the tray onto the hex grid to place it. Tap a tower to upgrade it. Long-press to open a radial menu right where your thumb already is - no pinching, no two-finger zoom, no reaching for the far corner of the screen. Everything lives in the thumb zone.

Each run is a bite-sized roguelike. Draft 3 towers from your unlocked pool, then defend through 8 fast 90-second waves on a freshly generated hex map. Climb the meta ladder between runs to unlock new towers and push your best wave higher. A daily seeded run lets everyone fight the same map and chase the local leaderboard.
