Insmouse no Yakata

Insmouse no Yakata is a 3D shooter based on a low-budget Japanese movie.
The gameplay boils down to the following: you need to find a way out of the labyrinth of corridors in the allotted time, shooting monsters on the way. For this purpose, the hero is endowed with a pistol and a limited supply of ammunition (which, however, in the necessary amount spread across the levels). In addition, you need to take care of health replenishment, look for keys to get out of the labyrinth and collect white and black balls. In total there are 13 levels to visit. There are four different endings of the game, depending on how well you passed the mazes.
Graphically, the game looks very weak. The rooms are not three-dimensional (the hero's progression is done by turning 90 degrees), the monsters look silly and ridiculous. However, a good concept, atmosphere and, in some places, "fun" sound effects bring the game to a rather high level.
The US version was not released.
