I have a premade puzzle game from CodeCanyon, built in Unity, that I need help configuring. The game is a puzzle genre and is already created, I just need some help with setting it up.

- Remote assistance through ANYDESK

Ideal Skills and Experience:

Additionally, I require some customizations beyond the initial configuration. Additional to configuration, I need various graphics modifications.
