This was a really interesting game! I liked the risk/reward and luck-based mechanics with the dice, it definitely added a lot of strategy. My only issue is that it felt weird how a single small bubble could completely deplete your health given enough time, so a possible solution could be to have your O2 level increase by a little every couple seconds or so, and that could maybe even be an upgrade choice too. Just a suggestion though, in case you decide to continue this project outside the jam, (I don't mean to be a backseat game dev). Other than that it was really fun, and I thought the 3d transition effects were pretty cool too!
