The game looks very nice and feels nice to play. I do have a couple pieces of advice though. I think the UI could be much improved. To be honest I think just replacing the default Unity UI with just plain slightly transparent white boxes and finding a better font looks so much better. A crosshair would be really useful for interacting with small objects, especially with the lack of feedback. The gameplay itself was enjoyable and I appreciated the little tutorial at the start. Great job!
