The two rooftop projects

Text adventure

Build a small text adventure that runs in the terminal: a prison escape through five rooms. You read commands from standard input, one per line, and print what happens.

  • Starts in the Cell and prints its name.
  • go moves between connected rooms.
  • take, drop and inventory manage items.
  • The locked door needs the key.
  • Unknown commands are handled.
  • Reaching the exit prints the win line with the move count.
  • The scripted walkthrough in the brief produces exactly the transcript shown.

Maze generator and solver

Write a program that reads a size and a seed, carves a random maze with a recursive backtracker, finds the shortest path through it with a breadth-first search, and prints both as ASCII art. Because the random numbers come from a fixed generator, the same seed must always give the same maze, byte for byte.

  • Rejects invalid sizes.
  • Prints a maze of the right dimensions.
  • The maze is a perfect maze (every cell is reachable).
  • The solver finds the shortest path.
  • Output is identical for the same seed.
  • The path is drawn with dots.

Questions

Do I need to install anything?

No. Everything runs in your browser. For the projects you can also work on your own computer and upload your files.

Can I skip what I already know?

Yes. Once you own a tower, each floor has a skip test: score 8 out of 10 and that floor opens.

What is the refund policy?

Refunds within 5 days of purchase. After 5 days, no refunds or returns.

Do I keep access?

Yes. A tower you buy is yours, with no subscription.
