Nice! Environment wonderfully detailed for a quickly developed game. Good fit with Jam theme, but perhaps if the player must collect objects/artifacts, it could be something real, like sea life, shipwreck parts to build something like a sub, or if its is going to be something mineral, gas hydrates or manganese nodules or something. Would be nice to be able to leave the seafloor and swim, even if only for limited time. Thanks for Jamming!
