Quick question; do you mean you're unhappy with the number of errors there are, or purely don't like the way they're animated?
Only asking because I've never seen that one myself

That is a funny one. Personally, I quite like how the ball can literally bounce off your foot and go anywhere rather than a set of pre-determined 'failed touch' animations (for want of a better phrase!).
Nope! Pretty much happy with everything in the game right now.
I'm also not expecting or asking too much from the game, unlike the previous years. I pretty much accept the game for what it is.
I just mentioned it because the demo being patched/tweaked has been talked about.
And that is the number 1 thing I noticed the first time I played the demo, but can't remember happening this last couple of weeks.
But then, I'm not really looking for the flaw in the game. I just enjoy and play. I don't even want to test things(and be technical, recording my games with gamepad viewer and analyzing each of my goals and errors.

) like I use to do in the past.
As a matter of fact, I didn't notice that I'm playing PES2020demo with a broken DS4 for about 4-5 days(out of 2 weeks).
I thought my passing/shooting direction errors was just added errors in the game.

And I'm very much convinced I sucked at this 2 aspects(shooting/passing) because I'm still adjusting to the dynamic wide camera and Dualshock 4 (got used to modified fanview and xbox one controller in the past few years).
I've only noticed my Ds4 issue when I play against a cousin on Steam and my diagonal passes/shots are always going to either towards 3 oclock or 9 oclock. Finally, tested it with HTML5 gamepad tester.
Here's my DS4 issues. Rma'ed and just waiting for the replacement.
Bought a new controller while waiting as it's not possible for me not to play this game for even a day.

I'm very lucky, my wife is supportive of my PES addiction.
