So once I realized that you had to walk through the revealed wall to reach the next level, it made more sense. And then when I realized the levers were hidden around the level. However I gave up on the maze level because I found the lever right away but couldn't find the exit. Maybe if it was highlighted or otherwise shown to the player, it would have been easier to find.
I like the puzzle/escape room-ish idea though, and I liked how you did the two puzzles I tried. Good ideas.
