Hey thanks for taking the time to give feedback on the spawn rates! We do have plans to up those given performance has been stable for the most part across the downloads from what I can see!
As for the password, that is a Dev tool that I left in to let people who wanted to figure it out, could. Ill be transparent, there is no gameplay there other than some vague hints to have it solved. I have realized this is a mistake and will be updating the "puzzle" to be solved through an organic way as it seems a TON of people enjoy that as a real puzzle. Sorry for the trouble friend!
