First of all thank you for your time and feedback, we really appreciate that! And yes, we understand that the whole mechanic can be really confusing at first…
The HMS Codes can be found within the logs and through hints in the puzzles.. now I don’t know how far you came but essentially the first few ones can be easily found within the Logs. Make sure to check your surrounding with the device equipped. Once you spotted a few holograms things should get more complicated as the codes are hidden in the environment. Look at the objects closely and also don’t forget to look at the symbols on the door in the second room as this will be your final code for this game :)
Hope that makes it a little easier… we do plan on further developing it a little more since many people did actually get stuck especially at the end since it’s not as obvious as we hoped it to be.
