Very nice, especially for a first! You managed a large map with a lot of detail, in 3D no less.
My critiques: The biggest one is movement. The turning was very sharp and it made it difficult to control the character. I also think the collisions on the bottles could have been a bit larger. I found myself with running circles around them trying to pick it up. The next is scale. Like I said before, it's impressive that you were able to make this big map in a short time, but I feel like if you'd scaled down, you would have had time to add more polish, such as sounds and more complex game play. Right now it just seems like a running simulator on a large map with not much else to do. I think scaling down would have made the danger more real and finding the bottles less tedious. Overall great work and I hope to see your next game!
