Anyone else picked this up on Steam this weekend? Got 15% off so currently £8.49. Well worth it for that price IMO.
The game is pretty standard by platform definitions and can be a bit frustrating at time trying to work out the correct path and having to redo the same bit over and over until you get it right, but the story, visuals and puzzle solving make up for that.
:edit: Actually, one thing to note, you might wanna remap the crouch key, as sprinting (holding shift) and rolling (hitting CTRL) at the same time can be a bit awkward.
