Well, it is unfinished. The screens of just the mouse are probably not in-engine and I don't like the lighting setup, threepoint just doesn't work well on cartoon characters.
Anyway, I like how Mickey looks on the ingame shots, his position and expression seems to actually fit into the environment, looking carefully downwards in mid-air, pretty unhappy while fleeing from a foe, happy while standing next to an ad of himself, etc.
If anyone knows gameplay it's Warren Spector. Deus Ex is still held in high esteem today despite its aged graphics and so is Thief: The Dark Project. System Shock got overshadowed by its sequel but that's still held in very high regard.
