Thank you so much for putting this file together!
A few things I modified, not sure if they are bugs or not. If you are dashing (I only tested with horizontal 2-way dash) and have directional snap on, the dash will basically instantly end if you are not holding down a directional button. I put a check for !dashing on line 401 to fix this, so I can have a full length dash without holding the left/right button.
Also one more thing, I believe this is a bug - if you are holding right, then tap left, and continue holding right, it will now dash LEFT instead of right (and vice versa). I fixed this by changing wasPressingR to wasMovingR on line 553. I also had to change 571 and 573 to have 0.1 velocity instead, otherwise you could still dash backwards sometimes.
Overall, absolutely incredible work, brilliant default character controller, and I feel like I learned a lot just from reading the file. I'm going to use this for basically every project :)
