Im glad it gave you a good scare :^]
I am very into old foreign cartoons, so I looked into GIFs of old Russian and Japanese cartoons. I essentially reduce the color count of each GIF and apply my selected color palette. After that, I just scale down the image size to fit within the screen of the TV sprite. There are a few channels that I drew myself, and those are meant to have multiple phases such as the 'smoking lady,' the 'tree,' and the 'laughing face.'
Thank you so much for checking out the game!!!
