What I played was great. The audio was good as well as the overall concept. Art-wise most of the 8-bit sprites are solid--the character and some of the machines in particular. I think all it needs it a little consistency. The wall and floor sprites look like the pixels are much bigger than the other assets which creates sort of a mismatch of resolution. It might be cool to also play with some dither shading and a more limited color palette (cohesive art style).
That said, saw your post on the discord about the art style--honestly the critiques are minor and overall looks pretty good.
