Thanks for the feedback, guys! I understand concerns about the palette. I literally took the first thing I googled by typing "NES palette". Will try to use less saturated colors next time.

I have a feeling he's just going to let himself in. . Great job!  Very retro.  It reminds me of a Dr. Seuss movie I used to watch when I was younger.  Good, albiet spooky, nostalgic feels.  Great work!  

I love it! Especially the kitchen one.

I feel like it might be worth it to tone the saturation down just to make up for the fact that modern screens are brighter than 80s CRTs were. Those old games have very saturated colours when running on modern screens, but they didn't look that saturated to people playing them on the technology of the day. Looking at these bright colours over the course of a game lasting more than a few minutes is likely to cause eye strain.

I dig the clean look of these. Everything has a sense of volume without going overboard with shading. Good use of a larger palette for that too - just enough to give things volume, but not enough to feel too colourful.
