Flagellum

Evolve a Cell is a free Roblox simulation by Splitline: Creative. You play a tiny cell in a pond, eat plants or hunt other cells (including players), add body parts, paint your creature, and grow toward giant bosses.

No code string has been published on the official game page, and placeholder labels are not codes. The in-game redeem button, if one exists, has not been confirmed.

A gameplay video of this experience says to press Space to dash. Other keys such as E are pressed in that video, but the video never explains what E does.

The official description names jaws, spikes, eyes, and tails, and says you can add more. Players have also named antenna, drill, leech mouth, zapper, tentacle, poison sac, flagellum, and stinger. Stat numbers for those parts are not published.

A player at level 6 said the game required them to colossal before level 7. The exact requirement was not explained. Open Stats and unlock any yellow entries, then read the prompt on your own screen.

No. A player reported 50 rebirths and still losing fights. Rebirth exists, but the reset rules and reward numbers are not published.
