Very nice executed game! The goal of the game is very simple, although when I didn't aim correctly the ball it would take a long time for the ball to stop completely so I can try the level again.
Maybe you can add a detector that if the velocity of the ball is low and there are no nearby checkpoints or coins, the friction will get bigger.
But overall really liked the concept and the vibe of the game! Great job!
Thank you for good comment!
About the issue with ball, you should be able to hold shift (or other button bound to the action) for 2 seconds and return back to launch at your currently set Checkpoint. Even while the ball is still rolling, you can reset to launch again. The ball will autoreset, when it is at very miniscule velocity, I didn't want to make it return early, because sometimes you can just barely make it to the checkpoint, bump the ball with a bumper, or get into force zone. You still have full control over returning back whenever (unless it's bugged, which I'm sorry about). You can also restart the whole level from pause menu or main menu, at least that should work flawlessly.
