Thank you so much! This is so in-depth and helpful! :o I'll definitely be keeping in mind what you said about the impact of the CG; I'll do my best to make CG scenes in future games nice and satisfying. ^_^
As for the unchanging vat scenery, Endless Mode may be what you're looking for. You can toggle it from the main menu by mousing over "Play" and clicking on the infinity symbol that appears. :)
Thank you again for the analysis! Comments like this are invaluable! :D
