The combat is fairly simple yet pretty engaging the more you unlock gadgets and abilities to solve puzzle, make more variation to your combat and expand your explorations
It's fully offline and has no in game purchase, for a game lower than 200mb, it is very good, the graphic is vibrant and somewhat relaxing, wide variety of enemies that makes you think how to deal with them effectively, hidden puzzles and treasures you and your robot companion can discover if you keen enough to find them, even the small interactions with npc that help increase your abilities.
Overall it's a good offline game, very recommended for you who love pixel hack and slash game.
