Thank you for playing it and glad you have enjoyed! To reach level 7 of Nascent Soul isn't easy, and you nearly made it to the end.
Agree with the feedback. We didn't get much time to make the stage visual look different after the player reaches different breakthroughs, though the BGM is actually unique to different level. For the weapon, it's true the current design can be a bit flat. We are rethinking to add more depth to it. Thanks again for playing!
