I personally use Unity as the game engine, Photoshop for art, Bosca ceoil to make music, and sfxr or Audacity for a sound effect, and of course paper & pencil to store my idea
I already use photoshop for a long time and I'm familiar with it, so it was easier for me to use photoshop and I have a pen tablet that makes it easier
Sketchpad 2020 is an online drawing apps and i personally don't like to use online apps or website bassed apps because I have some internet problem and I keep losing progress every time I use online apps
