Thank you for your feedback! I looked into it and you are right, the flipper friction seems too bouncy, very miniscule and hard to adjust. I've tested it a bit and noticed I forgot to add a line of code in the step event of obj_physics in the current version. I'll make sure to correct that next time I do an update. If I add this line here, the flipper friction becomes a lot easier to adjust using the FLIPPER_FRICTION macro.
(you may need to right click the image and select "open in new tab" to see it full size, itch seems a bit weird these days when handling images...)
