You can go into the initialiser sprite and play around with the custom blocks/functions and with the shapes you can draw. If you like what you've made, be sure to remix the project and share it because I would like to see it too :) Btw I did this because I am making a game and I'm kinda not that great at art soo... yeah...
If I see something really cool I will give you a mention here and on my actual game page, and you may end up finding your character in the game once it is out! Credits for character art: [None so far]
