Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 18 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
This is a casual roguelike game where you become nanomachines to protect the human body from viruses and bacteria.
As time progresses, the human body ages and becomes increasingly vulnerable to viruses, bacteria, cancer cells, and more.

Nanomachines come with a power-up feature.
Acquire various weapons and eliminate external threats!
Viruses and bacteria become stronger over time, so strategically upgrade your weapons to stay ahead.

Nanomachine weapons can evolve into extremely powerful “Synthesis Weapons” when specific conditions are met.
Experiment with different combinations and discover them all!

・Focus on collecting experience points first. Start by defeating enemies you can handle.
・Survival is key in the early game. Master the art of dodging and running away effectively.
・Look for items on the map. Don’t miss chances to heal or power up!
・Find weapons that suit your playstyle. Your strategy will change depending on the combinations you choose.
• Actively obtain Synthesis Weapons to gain the advantage!
