Really loved your art on this. The shop felt real, the depths felt real and each of the dinosaur designs were unique. Had a little confusion on some of the navigation controls, so needed to re-read your instructions more than once (would've been great to include in game)!
I think the core concept was interesting, but the rock/paper/scissors gameplay felt entirely random each dive. Might be cool to add some kind of indicator when you're picking your team of what they're up against so the user input feels like it matters more.
Great start on this for a 3 day jam and could totally see it being developed into a fuller game!
