As a side note, although it's amazing to create your own music for your games, if you are running short of time or just want to see your game see the light of day as soon as possible, it's not mandatory to create your own music from scratch everytime. We have some great soundtracks too if you are interested in getting some for your game and most of them are Absolutely Free!! Feel free to check them out and best of luck for your amazing games 😇
