Very solid! This has to be the most ShadowDark adventure I've seen for the jam so far. Definitely less gonzo (which is also awesome, its just good to see some variety on the gonzo spectrum.)
I really like the near-identical room keys for the two schools, really creepy moment for the players to cotton on to as they explore. Smart players will realise the school of Korreg Lem is not a great place to return Leffa to. I think you did a really good job incorporating the inspiration into tangible gameplay with the platform mechanics.
Overall a very measured distillation of the NES games you were given, well done!
