FF6 Tenkarider's contest (accessible even to casuals)

The downside to this task in my opinion is that the puzzle hinged on being able to guess a weird game mechanic like being able to remove some weapons of some characters, but only in battle and not in the menus. It requires a lot of moon logic to figure something like that out. For something like this, I feel like the player should go into the challenge with enough knowledge to know and/or guess at a strategy right off the bat. Of course experimentation will be necessary to get a better time than you would otherwise, but the player should be able to at least guess what they should experiment with. In that regard, maybe you should be more transparent with weird things like that instead of making them "puzzles".
