The music was getting me pumped to see my character in action, next time I hope!
The art was really great, you nailed the aesthetic. I've wanted to make a similar system to procedurally generate portraits, but could never get it to look right (maybe the trick is to keep the head shape static).
The UI started off a bit tricky (I thought I was stuck when trying to input my name), but was overall very functional and intuitive, but I found the buttons to cycle colors through trial and error (just looked like a blank square).
Great work!
