I picked Easy at first because I wasn't confident I'd do well. I was shocked and a bit disappointed when I completed the goal, I wanted to keep going! And I will, I'm definitely coming back to this game after the jam is over.
The explanation of everything at the start explained things really well without an overload of information. The systems are satisfying, the camera shake and mechanical noises of adding a new section feels great.
When the first raiders attacked I thought I was immediately sunk, I hadn't built any defenses at that time. Luckily the station handled them without much fuss. It seems to me that they go right for the core itself, so the best strat is building a junction first at each spoke, so that defense turrets can be placed in the most effective positions.
