This is a very well-done piece in a good cause, but it would have been nice for the author to acknowledge the very obvious inspiration from Monument Valley - https://www.monumentvalleygame.com/mv1 - particularly given they're asking for tips.

>The idea for parallel paths and the illustration style developed independently, but the team did take inspiration for the isometric world and user experience mechanics from the game Monument Valley once made aware.
