I am attempting to make a custom character and I believe I am using the wrong software for converting a Piskel made sprite in .png to the base64 code, as choosing my custom character crashes the game. The site I used to convert the sprites is https://www.base64encode.org/
EDIT: I see that I might have used the wrong type of encoder.
2nd EDIT: It was a wrong encoder, for anyone reading this with a similar problem, specifically look up png to base64.
