The idea is very nice and incorporates well the theme. The graphics are very minimalist but design wise it is very satisfying to see the little cubes fall each clicks, although it can get a bit buggy with unity physics when one spawns inside the other.
The UI being one of the only visual elements could get some more work because as of now it is just too little and since there is not much else on the screen the UI needs to be more interesting.
If you have the time please rate my game, it would mean a lot to me!
Thank you.
