Because he does not have a mouth, he expresses emotion by curving his eyeball. This was trained with "happy" and "angry" to reflect an upward or downward curve, though you can do other emotions.
It tried to train with "detached arm", since he has that effect going on in the game, but it does not work very well here. Try it if you want to give it a shot.
Wildcard set: gmageverhood, 1boy, solo, one-eyed, wizard hat, green cloak, green hat, purple skin, {white pupils|ringed eyes, blue eyes, purple eyes}, {happy|angry}

I loved Everhood when it came out, but noticed there was next to no models out there for the game. I figured I would give it a shot.
If you haven't played Everhood, go and do it, it's awesome. The music-based combat is on point and the vibe is different enough from other absurdist titles like Undertale to capture the niche in a way that matters.
Here is his overworld theme is you want a demo.
