With some adjustment it could be a great game!
I like the concept, but it’s a bit boring, it’s just about getting sticks and staying in the fire, also, you can survive without fire because wolves gets stuck in trees sometimes.
The limitation is respected, because you pick-up and drop items with one button, but it could have been way more fun implemented in a different way.
I don’t understand why you can move only with arrows and not with WASD or with a controller, as you are using Unity, I recommend you to do some research about Input.GetAxis and Input.GetAxisRaw, because that automatically let’s you detect WASD, arrows and controllers inputs!
The art is quite good, and overall the game is not that bad, considering that only one person made this, I think you should someday remake this, spending more time on it, and it will be a really great game, it has good fundaments!
