A bit on the hard side to be honest. Some hallways are very long and once the time starts ticking it's a bit frustrating to have to plan half the time to run through the extra long escape corridors. Apart from that, nice take on the theme.

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.
