Generally the hardest thing with version control on a database (for an evolving codebase) is separating unrelated changes - such as schema changes vs content updates - and branching and merging those changes in sync with the code dependencies. Another issue is non-destructively replaying development changes into test/production environments.
So for example, you might have a feature branch that includes some schema changes and some value modifications, and a content branch that includes a bunch of inserts into a few content tables that happen to include foreign key references to each other (so you need to maintain referential integrity when replaying those updates/inserts).
I don't see anything in the description that indicates this tool address those problems. For me, those are really the only problems that a DB version control system ought to be focused on. Speed of snapshotting is not all that important in a development environment as you typically work on a cut-down dataset anyway. A minute or so to take a snapshot a few times a day isn't a huge deal, whereas taking more frequent snapshots doesn't seem like something that adds any value, if it doesn't address any of the other problems.
