This looks like the foundation of a cool crafting-style game. As others have observed, there isn't a lot that can be done at the moment as there aren't clear controls. But as a WIP I hope you continue working with this idea as I like the Don't Starve style of survival crafting game very much! 

Thanks for submitting Survival of the Fittest to the SCREAM LITE jam! 

I was a little nervous to boot this one up with the complete lack of description on the game page. But it was pretty neat once I got into it, I loved the visual style. The symbol for the darkness/antagonist meter in particular looked very neat. It took me a second playthrough to actually grab the axe, it's got a very pixel specific grab zone. But with that accomplished I successfully made a campfire with my ever-growing supply of thousands of logs that started accumulating in my inventory on their own. I'm guessing you didn't get accomplished what you wanted in the timeframe, as I didn't see any way to deal with the food bar. But I like the survival premise you were going for. 

Maybe you have to write something about the game, no idea what to do .

You forgot the colliders on the borders..
