The visuals and pixel art look really well made.
There doesn't seem to be much in regards of gameplay though.
Additionally, you probably should not rotate the pixel art when placing it, as it looks kinda weird. You can see this clearly at the Main research computer node, where you used the same art but rotated.
The music fits the game's esthetic well and is kinda nice to listen to.
Overal, with a bit more gameplay, this could be a nice little pixel art game. Good job.
