Great! I love Peglin so this was easy to get into, I haven't made it too far yet but it's really fun.
I think a speed setting would be a good addition, I usually play Peglin on 3x because the default ball feels too slow for me to be honest
I also think the game should be paused when the hints are open but that's not a major problem, you aren't able to aim before your first shot (which happens when clicking close for the hints in my case)
Great work!
