## Description
_Rockfall_ is a Boulder Dash variant. It is not related to the Atari ST
series with the same name more than being inspired by the same game. Like in
the original game the objective is to collect a certain number of gems in each
of the game’s levels. At the same time falling boulders have to be avoided
since being hit by one leads to a loss of life. There are also some creatures
moving around the caves that the player can kill by letting boulders or gems
fall on them. Some of them will then be turned into gems. There are also bombs
that can be collected and used to kill the creatures. Once enough gems have
been collected an exit will open that the player can escape through. This all
have to be done before the timer reaches zero.
