As someone who made an incremental game I wish I could've thought of a way to make it as simple as yours. A few upgrades and the prestige or level system give you a goal to work toward. Very well designed for how simple it is, I will say the auto upgrade I started avoiding because I felt it only messed up my spinning. I made it all the way to 500K one btw lol. The popping is also very satasfying. Great game!
