Hey, cool looking map. I get that people prefer 3d build, but given the theme I think the pixel art fits well.
It simple, but it still looks clean. I just think the Pac-man looks a bit weird.
Not really a fan of the slabs used and I would change the netherbrick and dark wall to a brighter colour.
I like the small details you put in the floor, just not sure if the glass and glowstone fits.
