Hey there! While playing I did notice somethings that kept me from liking it.
- The Camera is too close
- Perhaps Zoom out based on velocity so you can see where you're going to land, or pan the camera down
- The player falls at such a slow rate
- You could increase the mass or gravity in the rigidbody or bypass it all together and write your own. A lot of games also implement a higher gravity scale when the player is falling for a snappier platforming experience.
Nice job!
