Clicking on the red spheres and seeing the character's annoyed sprite is oddly fun!

The highscore system is also neat, it does encourage you to try to beat your own score.

I do think that maybe the way Mr. Cube scores points could be improved?  

It seems like Mr. Cube will inevitably score a point for each sphere in the game since all of them get shoved aside at some point, which makes stunning Mr. Cube aside from the point deduction feel insignificant.

Props to Mr. though, he is very good at prioritizing what spheres to push!
