Time can be cruel to even the most innovative of games (look at Knight Lore or Sabre Wulf!), but not in the case of these marvellous First Star boulderamas. The idea's simple, the execution's brilliant. Move Rockford around the grid collecting diamonds and avoid being crushed by boulders that attempt to splatter you as you pass. You'll also have to block growing amoebas, transform butterflies and outmanoeuvre fireflies. Terminally addictive.
