Boulder Dash/バルダーダッシュ (Nec Pc-8801, 1984, Comptiq/First Star Software/Peter Liepa/Chris Gray)

This is Boulder Dash/バルダーダッシュ for Nec Pc-8801, and the gameplay is fast, so I tone down the speed for this one. As you progress through you will be bombarded with a mystery block that increases for every boulder that blocks it way. If you get caught by the Square, Butterfly or get squashed by boulder you will explode forcing you to try again. This is a well-known version to me because I've play for some times, rarely do I make a video on this game.
