Use arrow keys or WASD to move. This game is not the main game and won't receive updates (if the main game ever does) Earn survivals by going through a round without losing all of your health. Your streak is dependent on how many rounds you survive without dying. When a round ends, your health will be set to the max.
This game has less content in cases your device has less memory space and can't load in everything from the other version. This version mainly has less audio than the main game to drastically decrease how much memory scratch uses when loading things in.
