Volvox

The Trimoebas are unicellular rolling animals that populate the primordial soup. Their dream is to build the first multicellular creatures. To succeed they will have to dig tunnels, build towers, and construct bridges, having no tools but their triangular bodies and their special abilities! Using just 7 of these abilities, Volvox offers 250 hand-drawn levels, for about 60 hours of play, and that's without counting achievements and stats!
