I second the review of TeslaCool; the game isn't enough challenging. May I give you some suggestions?
- Decrease slowly stamina over-time. Food will increase stamina. So, by doing nothing, you'll essentially starve to death.
- Show the health / stamina on main screen (the 3D view).
- Do an opportunity attack when fleeing (one hit from the deer to the player). Fleeing should be risky.
Also, take a look at the following game, that are using the same gameplay tropes than yours:
- Don't starve (PC, Steam)
- Lost in blue (DS)
Still, keep up the good work, I would not be able to achieve a 3D game in such a short time period!
