Griel’s Quest for the Sangraal

Griel’s Quest for the Sangraal is an MSX1 remake of the old MSX2 puzzle game,
Gurieru no Seihai (The Holy Grail of Griel) by Momonoki House, first published
in Peach Up 4 in 1990.

The gameplay is similar both to Soukoban and the Lolo games, though the focus
is not on moving boxes around. Instead, you are a knight who must pick up
magic objects to vanquish evil creatures. The following objects can be found:

* Magical Staff – Vanquishes RPG slimes.
* Holy Cross – Vanquishes ghosts.
* Sacred Sword – Kills ogres.

Only one magical object may be carried at any one time, and it cannot be
dropped. The only way to get rid of an object is to use it against an enemy.
Just as in the aforementioned puzzle games, the emphasis is therefore on
picking up objects in the right order. This can get very tricky not only if a
monster is in front of a desirable object, but also if it is behind an object
which you can’t pick up or can’t use against any enemy within your reach. To
complicate matters, many levels contain tiles which only allow movement in one
direction, so that one can easily get stuck and must forfeit. Luckily, the
monsters are immobile, so that at least timing is not a variable in the quest
for the Sangraal. To aid you in your quest, you are given a password every
five levels.

This adaptation was made for the MSXdev ’05 coding contest.
