I don't remember the last version I played. Maybe it was the gameboy version?
The thing about the movement is that it feels like it takes time for my inputs to register and the time frame I have for pressing the correct button is too short. There is also a lot of changing directions in mid-air which is not easy to do. You as a dev are very used to the controls and mastered them, which means people can get to that level too. The question is how quickly can they do that.
