Nice concept, though nothing new.
If the jumping didn't suck so much, this could have actually been fun.
Reviews for "The Other Side"
I'm sure it's great. Looks wonderful. However, I dislike games that take over my scroll wheel and cut off half my screen unless you move the scroller on the bar- it's bad mechanics and I wish this type of interface had never become popular. It's disconcerting and unnecessary.
-1 star right at the start for making the game too large to view in a browser without zooming out. -1 additional star for making the game WAY too large to view without zooming WAY out. You need to zoom to 67% normal zoom in Firefox to see the entire play area. That aside it was a fun little game with nice music, art, and game play. A solid 3 stars.

So the premise is that it's a platformer where you can't see things that are about to kill you reliably? Seems fair.
This game has the same issue that 3D games have to deal with; you have to juggle moving and looking simultaneously, since both are dependent on one another. First person shooters deal with this by having cover where the player can sit stationary while they aim, and by having a wide field of view, meaning the player can focus on moving or aiming one at a time. This allows them to master the controls more and, eventually, do some pretty clutch, coordination heavy things. This game fails to do either effectively; there's no practice lead up section, the area revealed by the mouse is so restrictive that no amount of practice would be enough to prepare the player anyway (fully prepared is the point where they can beat every challenge). To counter this, you made the game easy, the ultimate insult a designer can give to their game.
To fix this game, I would make it anything but a platformer. The conflict between the controlling and the looking is central to what's holding this game back. Maybe a stealth game, lending itself further to the horror theme? Or a puzzler? The beauty of platformers is the very fact that moving simultaneously moves the camera to follow you.
