Firstly, thanks for the feedback.
I'm glad you liked the puzzles and "combat". I think it's kind of funny being made in RPGM but not using the RPG combat, but it saves me a lot time involving balancing and additional mechanics.
Hmm, that gives me an idea actually. I've been kind of unsure about what to do about the casino, but now that I think about it I could put the saved NPCs in there so you can talk to them after being saved. If I do that it'll be with the extra storage modes update.
I did add a little bit of additional dialogue for the lab NPCs. Both the Drs have a multiple dialogues and Miranda will mention she ended the lockdown to Shelly and Gregory. I was considering having Miranda interact more than that but that will have to be later.
To answer your question, I might increase the max size a little more, but it definitely won't go beyond the limit of 2000. I'm not sure if people can even tell, but at the current max size there are a few images missing, which is part of what I'm going to rectify with the next update.
Also, I'm betting that someone is going to do the whole lab and not touch a single locker and then learn that they can open the lockers somewhere else.
