There's some pretty neat ideas in here! It would certainly be cool to incentive better performance as a bonus as well as refining the controls to be more precise. While you can aim while jumping, there was the idea for letting you aim while running around as well, but I didn't have the time to complete those extra animations in time unfortunately.
Multiple coins in a level could be fun to design for, though it might make the whole "one throw" bonus idea a bit blurry, maybe it could be "minimum throws" instead...
Thank you so much for the detailed feedback, I'm grateful for it! (＾▽＾)
