That’s actually a good way to think about it, the puzzle levels are basically a replacement for the combat mechanic, if done well it’ll likely engage you more then selecting weaknesses.

It’ll also permit you to get different grades of rewards on a much wider scale depending on how good you are at that sort of thing. There are decent reasons to support this, not the least of which is someone is trying something vastly different. We can’t tell yet, but this might be a JRPG *without* a combat mechanic

It could solve many problems normally laid at the feet of JRPGs.
