I enjoyed the music, relaxed atmosphere, and the over all idea.
I did however immediately find out that planets don't increase in price when you buy them, so I spammed them until my iteration time was 0.033 seconds, and so after just a couple minutes of play I had beaten the game.
Not to mention the text showing up on the left part of my screen, I sent you a picture in discord.
All in all:
Style and idea good. The mechanics need to be balanced.
