I really liked the first episode. The characters were endearing and you've set up a fairly good premise. I think my favourite part is the very serious faux-umineko scary bit with 03 followed up by Lucy still not realizing they're robots and 01 being like "wow you really don't get it yet"
The art and music is really nice too, it all feels cohesive and easy to read and play. Good job! I linked it on my twitter as well so hopefully you get more players soon.
