Hey,
Thanks for the thoughtful feedback! We're working hard to get the balance and feel of the decompression just right. We want a balance between the reality of diving, and something more forgiving and fun, as well as UI features that help decompression zones be a bit clearer. As far as that bug, thanks for letting us know, we've already fixed it and will release a new version of "Into the Abyss" next month, after the jam has ended.
