There are some really interesting mechanics in here .
like being able to trap the guard ( even if he does't do anything )
the spiderwebs where you can move through but objects cant are a clever idea
I feel like this could be a very interesting puzzle / stealth game
the only thing I found to be a bit annoying is the moving camera , maybe let the player move the camera with the mouse when the mouse wheel is pressed to avoid moving the player more than you wanted to
for your first game this is amazing
