For what it is I liked it

Controlling the ball was fun (but having "enter" key for jumping felt odd to me, why not "z" or "spacebar"?)

Was the game supposed to evolve with time? After a while a spike breaks the floor into another spike and than... nothing else happens? (I got to score 60 with nothing else changing)
And there is this ramp at the right corner because... ? After a while the game quickly became stale

I liked the design of the ball's face, everything else was not that interesting looking

The song was fine
