My name's Fraser and I've been messing with Unity for the past 6 years or so making small prototypes and games. Self-taught coding through learning Unity as well as improving my skills in other areas such as art and design. Some examples of my work are here on itch and available on my GitHub.
The software I currently use, from my experience these are super easy to use and tend to have plenty of tutorials to help beginners. They are also all free for personal/small buisness work except for Aseprite (which is definitely worth it anyway) :
