■ About the Game

A Deep Descent in Search of You

Moma embarks on a quest to find her friend, whom she thinks resides in the vast subterranean realm of Million Depth. Yet, the reality is fluid as the story of Million Depth alters across different timelines, and so does Moma’s destiny, adapting with each changing world around her.

Mom’s past choices carry far-reaching effects, echoing into the future and affecting multiple timeframes in ways that are hard to fathom. As she navigates her voyage, she must collect scattered hints to unravel a multitude of enigmas she encounters along the way.

Freeze Time to Strategize

In the heart-pounding world of Million Depth, I’m armed with an extraordinary gadget, a Biotope Jammer. This bad boy freezes time as long as I remain still. It’s my lifeline, my secret weapon against the array of treacherous creatures that skulk in the shadows. Whether I’m cornered by foes, I can buy myself some precious moments to strategize and find a way to outmaneuver them.

Moma’s equipment, such as weapons and shields, aren’t indestructible. In a fight, they gradually weaken and eventually shatter. This leaves Moma vulnerable without any protection until they’re fixed. But, when in trouble, the biotope jammer can be crucial. It allows you to pause time, strategize your next step, and safeguard Moma’s life.

Get Creative with Weapon Crafting

Moma can equip two pieces of equipment, both hand-crafted by combining different types of blocks.

Certain blocks can be enhanced when positioned alongside similar ones. Utilize them thoughtfully to create a variety of weapons, ranging from powerful sniper rifles to durable protective barriers.

Ultimately, your creativity is what will give you the upper hand.

Barter with Shopkeepers

As Moma travels along, various merchants will present her with crafting blocks, goods, and artifacts which have the potential to boost her skills.

In Million Depth, shops operate differently and don’t accept conventional payment methods. Instead, engaging in bartering with the shopkeepers is key to securing deals. To succeed, it’s important to gauge the worth of your trade items and the mood of the shopkeeper, as this can influence the outcome. By striking a fair deal, you could acquire valuable items at reduced prices. However, if you overstep boundaries and appear too greedy, you risk upsetting the shopkeeper who might then increase prices in retaliation.

Furthermore, not only does the underworld harbor an unusual commodity known as Stockinum, but its worth changes frequently.
