Yes, the difficulty of that dungeon got out of hands... here is a link to the map in the game guide that I hope helps: https://docs.google.com/spreadsheets/d/1nlO2owvibS5tvHbFyK83FGQc0PcGN16cWm7aq3Q4...
I was actually using the map lol.
If this is RPG maker, instead of doing it all over again, you could create a parallel process event on the main map for the construction site labyrinth that checks a variable(# of player steps) that when it reaches a certain #(whatever number you think indicates someone is struggling).
Though, you'd probably need to add a few events of the plushie or something helping the player by showing the way.
Here's a picture of example. Oh, happy new year!
