I agree that the controls are difficult to learn. I remember that I had the same feelings back then. Stick with it, though. Once you've got the hang of controlling FLUDD, you can be very precise and increase your movements massively, to the extent that you might probably miss him in a few certain occasions.
Thanks, I will stick with it. The first major hurdle I had was the first time not using FLUDD (the hidden cave) and yes, I missed him there! I just couldn’t get the hang of Mario jumping so damn far ahead, so different to other games. I guess that was partly due to removing the long jump but it feels I’ve less control.
