Superhero Drop and Save is a physics aiming puzzle: you drag and release a superhero at the villains holding hostages, and the hero neutralises them with small explosions on landing.
The explosions are indiscriminate, which is the puzzle — a throw that takes out three villains but catches a hostage fails the level.
The explosions damage anything nearby, including the hostages you're meant to save — so the puzzle is finding angles that hit villains without catching civilians.
Yes — new hero skins from the market, bought with money earned from levels.
Yes — drag and release. Nothing to install.
