I like some of the environment models but they were hard to see due to the player's camera.

Welp! As your first game, glaring flaws are par for the course. So here you go:

• Controls are disorienting. It started fidgeting quite a bit when I moved.
• I can easily go through walls and stuff(but I guess that shouldn't matter since I'm a ghost?). 
• I feel like you should limit the player's ability to change field of view. The player can get to some extreme values and it gets confusing. 
• Also it tends to freeze or instantly crash for some reason. 
• Jumping in the water can sometimes cause you to clip through the ground and fall down.
• Nothing happens when you fall down. I had to open the pause menu to restart

I successfully found Teddy and brought him back to base!

 The environment seems well done, but character controller seems to be in need of some tweaking, maybe some angle on the camera would help.  Also, some music would add a lot.

The camera movement is making me feel uneasy. I'm guessing it's because the camera also tilts along with the player. I had to stop playing the game because of it :(

it's a good start and concept. but needs polishing and fixes.  for instance character is too far. and I'm not fan of the controls. but it's good start in unity.
