A very very great game, I love the flashlight mechanic with the different lights showing and masking out different things! Also the wheelchair mechanic, although I've seen it in other games before, is done really well here!
The only two nitpicks I have is sometimes I felt directional audio was a bit too harsh (if I turn just a bit the audio fall off and increase is two strong on both sides)
Also I kinda wish the mouse dragging for the wheelchair was forward and back relative to the chair's forward direction instead of just a global up and down direction, I found myself intuitively dragging up because my character was facing down and I wanted to actually move back.
Overall, great game, great art, great audio, I can tell a lot has went into this, good job!
