EntropyLock

Entropy Lock – No tutorial, no text. All the rules are discovered by yourself.

▎ With each step, the player's color cycles from Red → Blue → Yellow, and only gates of the same color open. The core can only be pressed on prime number steps.

Hit a wall and the controls reverse. On the other side of the screen, your "shadow self" moves like a mirror, opening up new paths.

▎ ■ Features

▎ ・Language-independent design — playable by anyone worldwide

▎ ・Color cycle × prime numbers × inverted controls × shadows — a deep puzzle where four rules intertwine

▎ ・Those who want to play with short, focused stages

▎ All stages are free. No ads. Your intelligence is the only key.
