Hey! I'm so sorry for taking so long to reply. My life has been a bit of a whirlwind. You should be able to save by pressing the 'M' key on your keyboard. This will bring up a small menu. Select the 'Save' option and then choose a save slot for your game. If this does not work please let me know. In the meantime I'll look into re-writing the opening instructions to make things clearer. Thank you for trying out my little game!
