Ghost Rush! is a Mega LD dungeon crawler game. The movement thru the dungeon is simulated by prerendered videos. Unlike most other dungeon crawler games, the combats are similar to lightgun-shooters, where you aim with your crossair on the ghosts. The goal is to catch those ghosts and trade it for money to get items. The game consists of 44 floors in 3 different settings. There are about twenty different ghosts. In order to complete the game you need to collect 12 specific items to sacrifice them to a grave stone. Then you need to destroy all 13 ghostmachines in order to be able to fight the final bosses in the very top and bottom floors. The game can be completed in about 25 hours.
