Magic-Mirror

Play a C++ puzzle text adventure (?), defeat monsters at compiletime and runtime, and return the Magic Mirror!

How to play

Copy the contents of Magic-Mirror.cpp into your IDE or a website like https://godbolt.org/z/fWvbaraG4, uncomment the comments inside main and get the code to compile and run. You can use C++14 and above. The code does not compile in C++11.

I don't get it, the code doesn't do anything

Correct. The point is to find a way to get at the more or less hidden types required to progress.

Step 1 is to uncomment auto training_sword = and find a way to get it. The solution is auto training_sword = Town::Blacksmith::steal_Training_Sword(Town::Blacksmith::Back_Entrance{});.
Step 2 is to steal the Wooden_Shield.
Step 3 is to call Ruins::Dire_Wolf::slay_wolf with your equipment to get the Ruin_Entrance. Continue until you return the magic_lamp (for now).

I'm stuck! Help!

You are probably missing some more or less obscure C++ feature. Some of the following might help: https://en.cppreference.com/w/cpp/language/list_initialization
https://en.cppreference.com/w/cpp/language/friend
https://en.cppreference.com/w/cpp/language/cast_operator
https://en.cppreference.com/w/cpp/language/adl

I did it! Where do I post my solution?

Congratulations! Please don't. Puzzles are no fun when the solution is spoiled.

Thanks
