Cool game! and it even ran on my potato PC. I liked the wolf3D / early FPS vibe with the 2D mazes - and the 'YOU ARE HERE' signs were great for the hard of thinking (i.e. me).
Would have been nice to highlight what to do next after beating the trials - I wandered around a bit after clearing the shooting gallery - not realising I needed to activate the wall with the text on it to continue.
Nice game overall.
