Cool game! I really like the risk reqard system, where I need to decide wether it is worth it going to mine more money or if I should go back because I dont have enough ocygen, really interesting! I was slightly confused about the controls at the start because I didn't know I moved to dig, but I figured it out after a few tries. I though the block which shows you other blocks was an interesting idea aswell, and this game is overall executed very well, nice work:)
