The story is awesome!!! CU-T3 is so cut3 and I felt so bad when I saw the cutscenes :'((( my heart!!
I got a really funny bug during the boss fight, I died and at the same time the boss died, it opened the door and I could go and save D3-4R while being invisible.
The boss fight was a bit tricky, and I wish there was a way to skip the cutscene at the start once you've seen it.
Loved it!!!
Edit: I love all the little animations CU-T3 does, like falling asleep or flying down from the sky at the beginnning
