I don't really know how I would improve a game like this, as there isn't really enough source material to go off of. According to the PCM Game Jam, the entire point of this game jam is to CREATE the backstory / lore of PCM so my feedback is really only limited to the gameplay.
Personally, I'm not a fan of maze games at all. This game was suggested by a viewer so I'm happy to play it for them, but otherwise, I just don't think maze games are very interesting. Perhaps a more narrative focus could have been more fitting for PCM but I understand that may be a bit out of your scope of skills if you're a beginner.
Thanks for making games!
