Add a magnet block to the game
This is a very simple idea that would offer a lot of possibilities!
Basically the idea is to add a block that has a North and South Pole and attracts/ repels blocks of the same kind. It could work similar to Connectors/ Mergeblocks by simply applying a force in the right direction within a certain range.
I imagine this shouldn't be too hard to implement and it has a lot of potential, you could e.g. literally build an electric motor from scratch or something like the hyperloop etc just to give you an idea.
This would be useful especially on planets where gravitygenerator-artificial-mass combinations don't work.
Thanks for reading and for all the hard work!
