Evaluation
LOST BUBBLES: Sweet mates launched on November 12, 2021. In the two weeks following launch, the developer shipped a flurry of patches and one content update: extra high-difficulty stages and a clear bonus mode were added on November 23, 2021 (Ver 1.1.0), followed by two more bug-fix and improvement patches through November 26, 2021. After that initial post-launch burst, development activity dropped off sharply. The only subsequent update was a server change in May 2022 (Ver 1.1.3), and most recently a security patch applied on October 11, 2025 to address a Unity engine vulnerability — the developer explicitly noted that update "does not change any game content."
There have been no major content releases since November 2021, no announcements of upcoming content, no roadmap, and no unreleased DLC listed on the store. The developer describes this as the seventh entry in their "low-price series," suggesting it was conceived as a compact, self-contained title. The pattern of activity — a quick post-launch polish period followed by years of silence on the content front — is consistent with a game that shipped as a finished product. The content can be considered complete as of the final content-bearing update on November 26, 2021.
Evidence
Ver 1.1.0 added an Extra high-difficulty stage and a new mode unlocked upon clearing all stages — the only post-launch content addition.
Security patch applied for a Unity engine vulnerability (CVE-2025-59489). Developer explicitly stated this update does not change any game content.

This is a hard action adventure game for the modern warrior who survives in a harsh society, depicting the smoothness of soap, the stubbornness of defying it while cutting yourself, and the sense of unity with like-minded friends you meet along the way. When your mind is worn out with frustration, the soap is also worn out, Literally, physically.
Game goals:
Control the soap, move, and dash to get to the soap holder. However, each time the soap is moved, its durability is reduced by friction with the floor. Please reach the soap holder before it loses its durability.
Feature:
Online multiplayer: There are quick matches and friend matches, both of which you are free to enter and exit at any time. In Quick Match, soaps from all over the world are trying to reach the soap holder at their own pace. In Friend Match, you can easily play with specific friends only by using one keyword. Up to 10 players can play together. Of course, you can also play alone.
Soap bubbles: When you use the dash, it increases your movement speed and produces soap bubbles. Because it's soap. Using soap bubbles with the soaps you're adventuring with is another fun way to make the stage look fantastic.
There is proof of life: Even when the soap wears itself out and ends its life, there will remain proof of your life (recovery items).
Other soaps (players) will have your proof of life and will never forget your aspirations and your way of life. Maybe, just maybe, they will.
Collection Item: After washing yourself with soap, you wipe yourself with a towel, right? Yes, you need a towel. Soap and towel are a set.
There is a towel somewhere on the stage. If you finish with a towel, your reputation will be high.
Growth System: Depending on the distance you move, your soap will become more and more durable and tougher.
It is the same with your mind. Never give up and keep going, and one day you will surely feel the growth.
Checkpoint: Touch a checkpoint to respawn from it at any time. However, you will lose some life when you respawn.
