I find that the game is a bit aggravating more than challenging. if you were going to make a game that is fully related to this concept, start with an easy level. And if you are going to make a full game like this, I suggest making the game more appealing. Not everyone is an artist but there are a lot of tutorials that can help you learn a simple form of art for game design: Pixel art. If you practice pixel art and use it for your games, they can look very cool. Also I noticed that the music stays at the beginning of where you spawn instead of being relative to the player. I noticed this after I leave where I spawn. Other than that, it is a good concept for a game. Keep it up.
