Ah, OK that does explain a bit!
At some point after turning off randos I mentally made a note that it would be a better game as a series of story battles, or possibly with on-map random mobs that you can avoid. Honestly, I don't like on-map battles unless you're fighting on the actual map Chrono Trigger style, so I think the best option for a post-jam edition would be to just run with the "no random fights" paradigm.
Not sure how that would impact your skill learning (though, really the same system would work in a longer game even without random fights).
But yeah, great job, and this entry definitely made me think more than most! (about the good and the bad, but mostly the good)
