In EFHD, you program the game as you play. You can modify and run source code to move, create, and destroy objects in this exciting and unique new simulator.

To progress through the game, players collect updates in each level. To find the updates, players manipulate objects in a charming 2D puzzle space, seeking out and executing .src files. Each new .src file allows the player to alter their environment by moving, creating, and eliminating objects. It will take both creativity and analytical thinking to make it through each level and find the update.

Functions and loops are waiting for you to test your programming skills. Are you ready to accept the challenge?
