thanks for notifying me on the bugs, didn't do a full check after uploading the new version. all the issues should be fixed now.
i think i understand what you mean with the flipping, but the rotation is still important to decide where the input/output of the machine will end up
the blueprints are going to be a bit more complicated than that since my code's a bit whacky for it.
i actually don't really like factorio personally. it's too stressful for me, that also played into my design choices for this game
