So first of all, big respect for making the game in C++! Unfortunately that's only going to hurt you because people prefer to play jam submissions in browser (though maybe you could compile to Web Assembly - not really sure how that works). I fully respect the effort though :)
Beyond that I did enjoy the game. The music was nice and relaxing (albeit a little repetitive), the graphics were nice (though it was kinda hard to identify controllable objects) and the levels were fun to navigate. I'm just not sure were the theme comes into play - though I'm sure that's just me being stupid
