Assuming you are talking about video game obstacles:
There are a variety of obstacles that players will encounter while playing video games, and each one must be cleared before moving on. Some common obstacles include enemies, traps, puzzles and platforming sections. Depending on the game, these obstacles can vary in difficulty, with some games being more forgiving than others. Players will need to use their reflexes, problem solving skills and sometimes even a bit of trial and error in order to overcome these challenges. While they can be frustrating at times, overcoming obstacles is always satisfying and is often what makes gaming so enjoyable.
