Some of it is clunky where it takes a bit to load, like the main menu or the UI of the ship, and even with selecting weapons it doesn't do anything. The radio in the corner works with the doors and moving aliens around and the aliens are good. It having 200+ songs is really big.
But some stuff isn't explained like how to shoot, what right clicking a weapon does or doesn't do. Charging jumps takes forever and the base game speed at 44% is funny, but slow and too slow.
I really love FTL and I hope this gets better in the future.
