hey Shogun thank you for leaving such an in depth response. This character controller was made completely from scratch so I'm glad to hear that the coyote time was the biggest thing you didnt like. The sprinting mid air was done on purpose to give a more responsive (albeit les realistic haha) feel to the jumps to give the player maximum control over their movement.
Also i did not have time to implement checkpoints or jump height regulation although i do understand your frustration as i also got frustrated play testing it haha
Anyways thank you again for playing, rating, and critiquing!!
