Hey! Thanks for playing, and for doing a video on the game. I really enjoyed it :)
Yeah, I agree about the health. Scrap metal was put into the game as a kind of "coming soon" for some kind of crafting or upgrade system that I wanted to put in, but it doesn't do anything right now. A bunch of people have suggested that it should heal you a little, so I'll add that in for the next small update. Thanks for your feedback, it really helps! And glad you enjoyed it.
