Impetuth is an arcade game in the style of an old MSX release called UndeadLine, where the screen scrolls in a vertical direction automatically and you lose a life if you cannot keep up with the pace of the action. Treasure chests can be shot at using the Z key to reveal treasures or power-ups, while invisible chests are only revealed after being hit by your weapon several times. Save a couple of civilians or knights, and you will boost your defense and firepower by some margin.

Only the third level is playable in this trial version.
