Supaplex

Supaplex is the first Boulder Dash-like game that is not fully grid-based: while the playing field is an obvious grid, the objects do not "snap" from one grid position to another, but can be halfway or "in between" grid positions.

Supaplex introduces a number of new elements that were not present in Boulder Dash, including bugs, pieces of base that randomly cause a life threatening electrostatic discharges, Ports, which limit Murphy's movement to specific directions, and terminals, which set off yellow Utility Disks.
