Eoroid

Eoroid is a puzzle game, a clone of the Commodore 64 game of the same name. Each level is played on a 19x9 board, with some of the squares having blocks on them and others being empty. When the player selects a board square, its state changes, and so does the state of the eight squares surrounding it, similarly to a "Lights Out" puzzle. The goal is to remove all the blocks.
