This was a really calming game to play at the end of the workday! I love that it was so easy to just jump in (figuratively and literally!) and discover the mechanics. It feels like it wasn't rushing me in any way. Like, I think one thing that would have made it potentially more engaging but also more stressful for me is if your oxygen tank refilled when you bounced on a fish, so you had to constantly keep finding more fish (kind of like how Downwell encourages you to do that with combos).
I also kept trying to grab things (like that yellow pumpkin looking thing, what is that? Nevermind, just discovered I can hit it with crabs) until I realized I could only grab the crabs. It could be fun if more things were grabbable as you went deeper in.
It would also be cool if this had leaderboards! How long did this take you to make?
