Thank you for playing and for the feedback!
The beacon system should help with the difficulty a bit if you use it to mark the dead-end hallways and the path from the key to the exit. That's basically the main mechanic but it's not very apparent from a first playthrough, I really wanted to include an in-game tutorial but couldn't find the time.
Also the maze generation can be a bit hit-or-miss and it's something I wanted to work on, occasionally you get really complex maps.
