Yes. She's very hidden though and requires solving a few obscure puzzles.
EDIT: Hints to reach Miku have been added to description!
wow, I actually found her and finished the game thx!!! This game is awsome, if you're still working on it I'm super looking forward to the final result this is amazing!! <3
Thanks for playing! I still plan to create a whole game, but it's gonna take far longer to complete. Probably a couple more years.
