Two major things going on! No, actually three!
First off - a long awaited feature by many has finally made it into the game: custom input support! You can now rebind your keyboard and gamepad keys and buttons to match your desired comfort. Currently there is a small issue with rebinding mouse input, but this is already being worked on.
Also a new game mode is introduced: Hot Mode. It's the most innovative game mode in years. Time moves only when you move! Enemies are a lot stronger now, but you can use slow motion to do epic maneuvers to dodge them now.
And the third major thing is that UNLOVED got a lot of performance upgrades! It now runs on the latest Unreal Engine version, which is heavily optimized on performance and I've added a new blood counter to fix performance issues when every wall is covered in blood.
Try it out ;)
