Thanks for the game!
I was so frustrating no to be able to access the other part of the maze! Yet another great project fell victim to procrastination...
Very nice floor and wall patterns! the screen is very densely filled with tiles, but it never feels cramped or too busy. And I admire your restraint in use of color: it would have been so easy to overuse the colors hack and make the game look too motley, but you've avoided it.
The level design and puzzles are of the highest quality! Maze mechanics are well introduced and strike balance between simplicity and complicacy. It's a pity there's only so little of the maze you can explore! The checkpoint system is neat too, although on my first playthrough I've headed immediately into the warp room and didn't know what combination to use to get out of it. So maybe 911 hint should be included inside the room too.
Also, I think I've noticed a bug: you can get onto the wall from a specific tile without ladder (see screenshot below)
