Hey, thanks very much!
I use a program called Aseprite for all of my art and animation. It exports as GIF.
Then I used an online conversion tool to turn all my GIFs into MP4
Hope this helps!
I don't mind at all! I make all of my 8bit style music in a program called famitracker.
It's totally free and there are lots of tutorials online for getting started. It's a bit of a learnibg curve, but worth it!
