I don't know how difficult people are finding it to get past the guards but if I tell them that removes a significant portion of the challenge. Perhaps I can find a way to hint at the solution by drawing attention to the area in the game.
Yeah that trap was devious :) If you look at the last window before the door you can see a bit of the guards helmet.
Thanks for the feedback.

When you get a certain distance from the guards they chase you and move 1.5 x faster. At the moment there is no warning when they are coming and as the resolution is so small you don't see them until they are quite close. Post jam I'll increase the resolution which might make it a little bit easier and maybe give the player some kind of warning when a guard is a certain distance from the player.
