Is this your kind of game?
For a microscopic survival journey with a creature you can assemble yourself.
Controls at a glance
Arrow keys swim and Space dashes on desktop. Touch uses a bottom-right joystick and bottom-left dash. Drag parts directly on the body, or tap Add for automatic placement before adjusting them.
Read the size relationship before feeding
Not every creature you meet is safe prey. Compare size and approach direction, then use movement to bring the mouth into useful contact. A brief brush is not the same as sustained feeding contact.
Food contributes to growth, and the gain receipt shows what changed. Watch the remaining evolution goal to connect small gains with the next step. When a larger predator arrives, preserving your current growth can be worth more than chasing one last nutrient.
Use the haven as your workshop
Follow the haven direction guide when you want a safe place to reorganize. Its boundary is visible, so you do not have to guess whether you are in the right area.
Start with automatic placement for a new part, then drag it on the body to refine the arrangement. Compatible parts can swap or snap into mounts. Try changing one function—feeding, movement or protection—then return to the water and see whether it solved the problem you noticed.
Keep assembly manageable
- Use the simple actions before opening advanced assembly options.
- Do not move every component after each small growth gain.
- Inspect the approach side when relying on directional armor; it does not protect every angle equally.
Progress & backups
The journey and unlocked endless record are local. Encrypted backup is available; there is no cloud account. Keep a file before changing devices or resetting browser storage.
