Ah yes, haha! You have to fight the enemy boss to get the access code. When you press [M] to see your map, you should see a B icon for the boss for areas you've traveled. Defeat the boss and you should get the access code. An Engage Screen should come up, press Y to engage when prompted.
If you have encountered a bug where the boss isn't spawning, please let us know. ^_^
Thank you for letting us know. :) We just updated the game! There was a bug where the access code wouldn't save between save files. We weren't able to reproduce the 'Coming Soon' bug though; that should only trigger after the 3rd and final floor (the demo's end). If you can share anything else about the specific bug you encountered, please let us know. Otherwise, please enjoy the updated game!
