The music sound credit goes to tallbeard.itch.io, but I did make the rest of the effects.
I'm not sure about the controls issue, but thank you for linking to the source page in case someone else runs into the issue (controls still work in my browsers currently).
Pinball physics is really challenging to get correct, but I'll keep making them until I get better. In this case, I found that flippers which allowed cradling felt bad to hit with (in this particular physics engine), so I solved it with these angles. I agree that it can make the table feel a bit oppressive, and would be better if I could solve both sides of the equation. Next time hopefully! Thank you!
