I have taken another stab at putting the "smash the printer, get stuck in the floor" bug to bed. I basically made the player not collide with the printer at all, and that seems to have stopped it. You can, of course, still kill the printer, with any weapon you like.
I have also greatly enhanced the player's chances of successfully rescuing a coworker. In the past, this has been a little too hit or miss for my tastes.
Having now seen several people post YouTube videos of their gameplay experiences (thank you!) I want to mention that one of my goals / philosophies for this game is to have it be very retro in its approach to the player; in other words, it will not hold your hand a lot. DOOM is one of my favorite games and a huge inspiration for this game. That's one reason why none of the weapons need to be reloaded.
I try to prioritize development time on features that will add the most to the game, as I am just one person and this is not my full time job.
