The submitted did not even try to answer the question about how the theme is incorporated. This looks like an existing project that was submitted to an unrelated game jam. The fact this was submitted to steam already and that there are no credits to the (beautiful) assets used, makes me think this was either done in advance or AI generated. I would like to be wrong but I see similar concerns in the comments below and the authors are not addressing them.
About the gameplay: it’s pretty but the controls are a little obtuse.
