Released on June 27, 2006, in Japan for Microsoft Windows, the game was only available in Japanese, but an English translation patch has been produced by Ian Kelley of AGTP.

The protagonist has a laptop MSX in his possession throughout the game, and can collect or buy ROM cartridges for it; many of these can be combined to produce various special effects.

The tension is created by arming many features in the game with various traps that can easily befall reckless adventurers, as well as several complete dead ends, from which, short of teleportation, there is no way out.

To this end, she created various "children" which were different races that roamed the planet that she tasked to find a way to send her back to the sky.

Taking the secret treasure of life after defeating the Mother, Lemeza escapes the crumbling ruins to the surface before it collapses on him.

Upon his return to the surface, Shorn surprises him from behind and steals the treasure for his own, leading Lemeza to chase after his father into the coming sunrise.

A build based on a mockup image by director Naramura[4] was made on November 6 of that year, which was kept private until the game's release.

[6] This was mistaken by most websites as an actual release, which was caused by factors such as language barrier and the game already being clearable, though it still lacks many features that would only be seen in the full game; a disclaimer about this was put up on the download page, listing "extra items, keyboard controls configuration, MIDI mode, (and) the opening cutscene" to be added.

[7][8] The PlayStation Vita version of the game sold over 300,000 copies worldwide within the first seven months of release, according to an announcement by Pygmy Studio.

[10] The game was remade from the ground up, development starting in 2007, and released on Nintendo's WiiWare service by Nigoro on June 21, 2011, in Japan.

Some other major changes include: Plans for releases in North America and Europe were canceled by Nicalis, its original western publisher.

It was released on September 20, 2012, in both North America and Europe without the downloadable content available in Japan, which implementation was supposedly the reason for its initial delay.

[18] Developed by Pygmy Studio, this release was titled La-Mulana EX and added a Monster Bestiary alongside some gameplay tweaks.
