I find this game lacks challenge; obstacles to dodge (like sharks) and a more critical oxygen mechanic would have added more tension!

I would agree, I had a lot in mind, only a small fraction of which I ended up implementing lol. I also made the upgrades and obstacles spawn rate easier last minute for the first build
I am working on making a second version soon, with actual obstacles like sharks, sea monsters, etc and I'm also going to make it so you go down instead of left to right.
