I'll comment on my experience
I felt frustrated. I felt cheated into a forced defeat(audio before inputs are removed could be helpful). At the end of the gameplay for the most part is about feel. And I felt the need to quit the game after colleting two coins on the right side of the map. The need to constantly check both space, A, and D while just trying to go to the left was counterintuitive.
If you forced me to platform my way to the other side, by needing to use all three button presses to find the coins it would have made for a more enjoyable experience.
