Hey, Thank you so much for the feedback!
About the second maze's door - its color coded.
One reason I can think of that may have messed up your code is the font, for example the image below is a 1, although it looks like a seven. So I will make some changes about that.
If I was wrong please comment what the issue was (if you might know).
About the third room - I kind of ran out of ideas and didn't want another code search maze, so what I had in mind is that this time the camera player needs to search for the code, but didn't have a good way to set it up so the ground player enters the room and needs to survive, I will change that as well as it is a bit too random.
Anyways I hope you enjoyed the game and will enjoy the upcoming updates! If you'd like to participate in private game testing contact me on discord - nomSpot#1596
