Dr. Alphys' Puzzle, from the game Undertale by Toby Fox, is a simple-looking tile puzzle with intentionally complicated rules. In this first-person re-creation, you must make your way from the Start Tile to a Finish Tile in 25 custom-made puzzles. You can even race up to 3 of your friends head-to-head to see who can solve each puzzle the fastest! Fight monsters, avoid piranhas, get electrocuted, and challenge your brain in Dr. Alphys' Puzzle!

This map also includes a level editor, so you can design and share your own puzzles!
