I liked Lost Memories a lot more than Code Embyro but I didn't think it was amazing either. It kinda felt like more like a fandisc than a true sequel since the plot wasn't as heavy.

That said I thought the first half was interesting because it actually featured a younger version of a Blazblue character from CP and gave her development. I just didn't like how a like 1/3 of the content was just watching a recap of the first game's true route events.

The second half of the game wasn't bad since most of the main cast were a bit more likable than they were in Code Embryo. As said above this part wasn't super plot heavy but I did like where things ended up by the end.

There were also a bunch of random nice heartwarming moments throughout that increased its score over Code Embryo.
