I can't say much because I can't play it because of the lag, but from what I see it is original and good.

try to learn optimization to remove lag, I recommend that you search on how to make "chunks" and light backing for games

Not overly challenging, but definitely a cool concept. Artwork’s nice, sound design is great. I do suggest increasing the default resolution to 1280x720 in the page settings so you can remove the recommendation for fullscreen, but if you have mobile support (which I haven’t tested) I can see why you didn’t.

Add to the description that "e" repairs the generators. It took me a little bit of time to figure that out. Other than that maybe a way to stop repairing something if youre accidentally standing in the dark when you repair it. Neat concept, I like the pixel art.
