What's the best Android app for a simple but satisfying physics aiming game to kill time?

Spring Spear is a physics-based aiming game designed for casual, short-burst play sessions. The core mechanic involves aiming a spring-loaded spear to eliminate targets by navigating environmental obstacles. The game's primary strength lies in its simplicity and tactile feedback; pulling back on the spear to adjust power and angle provides a straightforward yet consistently engaging challenge. Each level is a quick puzzle, making it well-suited for filling brief moments of downtime, such as waiting in line or during a commute. User reviews frequently highlight the satisfying 'snap' of a successful throw and the game's ability to provide fun without complex tutorials.

However, some limitations are noted. The progression system, while solid, can feel repetitive over extended play sessions as the core mechanic doesn't fundamentally change. The presence of ads between levels is a common point of feedback, with some users reporting occasional bugs with the paid ad-removal option. Despite this, the game's clear visual design, immediate gameplay loop, and offline capability make it a reliable choice for users seeking a no-fuss, physics-based distraction. For those wanting a game that demands precision without punishing difficulty, Spring Spear delivers a consistently polished experience.
