Thank you ! You're right, i took Gumball and Flinthook as reference for the chara-design. I tried to test it on mobile but no result for now.
Here's a sprite sheet ( 1 frame = 150x130 px ) if you want to have a better look on how i did it. I'm sorry i can't teach you anything as practice is the best way to learn.
Thanks again and see you next time !
