I was really stunned by the art the game, it's really nice to see but I didn't understand anithing about what I could do or how to do it so it got pretty frustrating soon. I'd implement some kind of tutorial.
Another small issue: there is a problem with the ui canvas in the main menu scene. In my screen all the buttons whereoverlapped in the center of the screen.
I hope you'llmake the game easier to understand because I like its style and I'd like to try it again.
