Complica DX

Complica DX is a "4 aligned pieces" board game with a twist: Whenever a column is already full, dropping a new piece will push down all others, so the board may radically change at every move. This game features multicolor animated graphics, AY music, and a very smart computer opponent (implemented using Minimax theory with alpha-beta pruning and heuristics) that largely surpasses usual Artificial Intelligence efforts for 8 bits machine with limited CPU available.
