Look's interesting mate, I'm a mobile developer myself, did you actually get the PEGi certification? Or does it come with Google Dev Console? How's it work mate, inform me lol.
When you go through the publishing process on the play store there are a few steps to go at. One of which is a content rating questionnaire. Your (as the developer) answers to this determine the age rating for each country/area that you release the game in. So the PEGI certificate comes from this.
Mine was very simple as it has no adverts, no payment, and no content that is unsuitable for any audience - so I can release everywhere to everyone.
This one was a quick simple game to remember how to 'finish' a game and the importance of going through the release part.
Nice seeing you here @grimbarian, I always liked the original version of this game you did way back. It runs excellent on my Nokia 7+ which is rather nice. I have a couple of ideas that would make it even better and enjoyable though
1. Rather than having buttons to move the bat, is it easy enough to use touch placement instead? For example, if you wanted to move the bat from the far right to the far left, its far easier to simply touch the place on the screen where you wanted it.
2. Since you're using game maker, is it possible to set the room speed to be 60 instead of 30? I always found the default speed of 30 to be a tad jittery and slow whenever I used it. 60 would make the ball bounces really nice and smooth on pretty much any modern device.
Still, I've played it a fair bit so far. It's almost as addicting as that soccer kick game I played on my breaks at work

Most other versions of this game that are available use the type of controls (or similar) that you suggest, but they never really sat well with me. So I wanted to do it my own way. I feel it adds to the retro-ness of the game as this was pretty much the way all games moved back then.
60(fps) would make the ball bounces really nice and smooth on pretty much any modern device.
Again, wasn't going for a modern take on the game - there's plenty of them around anyway. 30 fps helps with the number of devices that are capable of playing the game (I'm supporting as far back as Android 4.0!!) and keeps the retro feel of the game too.
