I almost thought this was same game that I had played on here & was confused for a while haha.
Story is intriguing. Art style is super nice.
The game balance is nice, I can just swim through without having to come to surface & can pick up ari from the 'shells' which is a good game design element as it doesn't break the calm flow that i was having with the swimming & doesn't make breathing a chore. The visualization of where you can breathe and not breathe was super clear as well.
The diving mechanic was a nice add-on to have. Also , not really sure what the bubble on the screen is for. 🤔(figured it out after I ran out of air lol)
