Hi Kurondie,
I agree the sound needs improving. I would like music and jingles but that's a lot to do so have kept it minimal until I can dedicate some time to that. I did have a sound effect on the slingshot, but it was triggering when the ball hit the opposite / adjacent sides so I took it out as it got annoying :). But it will be back once I have restricted it to the hypotemuse!
I like the idea about the chickens switching off. I will research what real-life pinball tables do in that situation.
Sorry to hear your score did not remain on the screen after playing. The game does attempt to save your scores to local storage. If stored successfully you should see your top 3 scores played in the header before and after you play. I suspect your browser isn't storing your scores for some reason. But I will update the game to ensure players always see their latest score regardless of whether the save to local storage was successful.
I'll consider the configurable controls. Or at least include more keys which trigger the flippers!
There are some graphical updates on the way so will see what I can do to improve those wheat icons :).
Thanks Kurondie for your excellent feedback.
