To me, this is a really nice concept. To have a small ship armed with a repair beam and use it to repair your larger ship with. Only one problem... You have to hit each individual block. This means you could miss some if you don't pay attention to every block. It would be a lot better if it repaired nearby blocks as well, sort of like a beam with a splash effect. So that way you can hit one spot and it will repair blocks near the one your beam is hitting. This would be a nice improvement to, what I think, is a nice feature in the game.
