Much better! The controls could still use a little fine-tuning, but you're definitely on the right track now.
And I know I mentioned this before but the graphics are really good! The reflections on the water are especially nice!
I was also able to deliver a letter to someone. With that being said, I only found the right animal by sheer luck. I've been a bit curious about the arrow in the upper right of the screen. I feel like it should be pointing to the next mail recipient, but it always points in the same direction, no matter where I'm facing.
A money counter would be nice to have too. After delivering my first letter it said I earned $10 but I couldn't see anything that kept track of my earnings.
I managed to figure out that the orange bar on the far right is your altitude but couldn't figure out what the blue bar next to it was. Adding some labels would be helpful.
So, still work to be done, but you're definitely making progress. I just recently started experimenting with 3D game design so I can sympathize with the difficulty involved. I struggle just getting objects to snap to the ground properly lol.
