too many issues. deleting belts left dark matter behind, no explanation on how anything actually works, full screen turned the game into a black screen with a white bar in the middle.
I see that you added the pages to the right explaining how the machines work, but the way they're placed makes it hard to read and easy to miss, and once you close one to read the one behind it, it's gone for good. Why not move them to the back instead of the side so you can see them all at once?
Maybe have the images on this page be examples of basic layouts for the players to copy and maybe figure out how they work, if that makes any sense.
I think you should be able to right click to get out of build mode, since you left clicked to get into it in the first place.
You cant properly see the current energy and energy per second while zoomed in because it's white on white.
Please increase the zoom speed, it took so long to zoom in using my mouses scroll wheel. Wait I figured it out you just have to zoom with the trackpad one time and the problem is solved.
And a personal gripe; why is the icon for the conveyer belt vertical?!
