I was thinking about that movie Escape Plan when reading this. I think the colors are a little much, perhaps a slightly muted color palette would make it more pleasing to the eye. The pixel art is great as always.
Regarding the contents I am having a hard time figuring out how to run it and keep the gameplay engaging. I like the premise of a prison break but the module seems to at have very specific information about the keycards and at the same the door puzzle doesn't seem to lead to anything.
