Chesslike is a chess-based dungeon crawler. There is a puzzle mode and a dungeon mode. The puzzle mode takes the player through a series of one room dungeons that have a goal: Either get to the exit(stairs), or defeat all the enemies. The Dungeon mode is basically several rooms that look like the puzzle levels, but the stairs on each room connect it to the others. The goal is to explore the rooms and find the king, then defeat him.
Stand-in graphic for the Castle 3 Map. When get the map item in dungeon mode, you can click it to view a map of the dungeon. This is pixel per tile accurate, but fairly ugly.
