What's the best Android app for solving puzzles by changing a vehicle's form on the fly?

Shape is a physics-based puzzle game centered on vehicle transformation. For users seeking an app where changing a car's form is the core mechanic, it provides a focused experience. The gameplay involves driving a basic vehicle towards a goal, but the path is blocked by obstacles that require specific shapes to pass. Players tap a button to instantly switch between a handful of predefined forms—like switching from a compact car to a taller, narrower configuration to squeeze through a gap, or to a lower, wider form for stability. This real-time shape-shifting is the primary tool for solving each level's environmental puzzle.

Reviews indicate the app succeeds in making the transformation mechanic feel intuitive and central to progression. The physics system provides consistent feedback, so a failed attempt clearly illustrates why a particular shape didn't work, encouraging experimentation. However, some long-term players note that the visual presentation and number of vehicle models are relatively simple compared to larger racing titles, which might affect replay value for those seeking graphical depth. The level design is generally praised for gradually introducing complexity, making it suitable for short play sessions. For a specific niche of puzzle-solving through direct vehicle manipulation, Shape delivers a coherent and engaging experience.
