There is a lot of glitches to this game. I like the interpretation of 2020, (I also thought of doing something that but didn't do it after) I get that this is a prototype so here is some of my feedback.
The UI is a little confusing and feels necessary as I have no clue what its for. The blocks have different heights and don't fit onto the playing space well. The controls and how to pay the game is hard for me to comprehend so it took me some time to understand when I read the comments from the others below this.
However, the graphics are great, the colours compliment well. The audio is calm and soothing which is nice. Great job! It has quite a bit of potential. :)
