The player skills are more or less for people to have an easier time if they don't have too good of a reaction speed. It turns out that everyone just gambles regardless and restarts if they lose, so that was unexpected. The main usage for the A and S skills is to change the spin speed, and D and F are for flipping the board (only really useful for making black slices accessible in the latter half of boss 2). I had a playtester complain that normal mode was too hard (I too was surprised at this information), so I'd rather keep it on the easy side for accessibility purposes because it's a jam submission.
