After my first 30 seconds of playing, the ball became stuck irrecoverably - neither activating the flippers nor using the "shake machine" function would dislodge it. I had to exit back to the main menu, and tried a different table. This time it took only 20 seconds for the ball to get stuck. Apparently this game has not been playtested at all, or the developer simply did not care. In any case, I would not regard it as playable in its current state.
Even without that gamebreaking issue, the game wouldn't actually be good. The tables are extremely simple - as far as I can tell, there are no missions and no different playstates. I couldn't even find bonus multipliers or extra balls, though it's possible that I just wasn't able to play for long enough to find them.
The game also has absolutely no settings except a windowed/fullscreen toggle. Keys are fixed to A and D for the flippers, Ctrl for "shake machine", and Space to launch the ball. You basically have to use your left hand to control both flippers, and you'll have to place your fingers at an angle if you use an AZERTY keyboard. Graphics are rather plain, and the soundtrack consists of little more than 5 notes repeated ad nauseum.
If you're interested in a cheap pinball game, I suggest trying the free tables of Pinball FX and/or Zaccaria Pinball. If these don't work for you and you want a few simple tables at low cost, then Malzbie's Pinball is also an option. "Lawnmower Game: Pinball" is, unfortunately, just a waste of your time and money - though at least you won't lose much of either.
If you're interested in achievements - it takes 12 minutes to get all 12 achievements for this game. If adding another "100%" game to your library is worth the money to you, then that's the only usecase I can see where you'd get your money's worth out of it. Personally I'd rather play a good game than grinding through bad ones just to raise an arbitrary number on my profile that no one will ever look at by a few more points ... but hey, different strokes for different folks. :)
